-# Cartoon Character Recognition
-
-Since the 1970s, face recognition has become one of the most important topics in the field of computer vision and biometrics. In recent years, traditional face recognition methods have been replaced by the deep learning method based on convolutional neural network (CNN). At present, face recognition technology is widely used in security, commerce, finance, intelligent self-service terminal, entertainment and other fields. With the strong demand of industry application, animation media has been paid more and more attention, and face recognition of animation characters has become a new research field.

-## 1 Pipeline
-
-See the pipline of [feature learning](./feature_learning_en.md) for details. It is worth noting that the `Neck` module is not used in this process.
-
-The config file: [ResNet50_icartoon.yaml](../../../ppcls/configs/Cartoonface/ResNet50_icartoon.yaml)
-
- The details are as follows.
-
-### 1.1 Data Augmentation
-
-- `RandomCrop`: 224x224
-- `RandomFlip`
-- `Normlize`:  normlize images to 0~1
-
-### 1.2 Backbone
-
-`ResNet50` is used as the backbone. And Large model was used for distillation.
-
-### 1.3 Metric Learning Losses
-
-`CELoss` is used for training.
-
-## 2 Experiment
-
- This method is validated on icartoonface [1] dataset. The dataset consists of 389678 images of 5013 cartoon characters with ID, bounding box, pose and other auxiliary attributes. The dataset is the largest cartoon media dataset in the field of  image recognition.
-
-Compared with other datasets, icartoonface has obvious advantages in both image quantity and entity number. Among them, training set inclues 5013 classes, 389678 images. The query dataset has 2500 images and gallery dataset has 20000 images.
-
-![icartoon](../../images/icartoon1.png)
-
-It is worth noting that, compared with the face recognition task, the accessories, props, hairstyle and other factors of cartoon characters' head portraits can significantly improve the recognition accuracy. Therefore, based on the annotation box of the original dataset, we double the length and width of bbox to get a more comprehensive cartoon character image.
-
- On this dataset, the recall1 of this method reaches 83.24%.

-# Feature Learning
-
-This part mainly explains the training mode of feature learning, which is `RecModel` training mode in code. The main purpose of feature learning is to support the application, such as vehicle recognition (vehicle fine-grained classification, vehicle Reid), logo recognition,  cartoon character recognition , product recognition, which needs to learn robust features to identify objects. Different from training classification network on Imagenet, this feature learning part mainly has the following features:
-
-- Support to truncate the `backbone`, which means feature of any intermediate layer can be extracted
-
-- Support to add configurable  layers after `backbone` output, namely `Neck`
-
-- Support `Arcface Loss` and other `metric learning`loss functions to improve feature learning ability
-
-# 1 Pipeline
-
-![](../../images/recognition/rec_pipeline.png)
-
-The overall structure of feature learning is shown in the figure above, which mainly includes `Data Augmentation`, `Backbone`, `Neck`, `Metric Learning` and so on. The `Neck` part is a freely added  layers, such as  `Embedding layer`. Of course, this module can be omitted if not needed. During training, the loss of `Metric Learning`  is used to optimize the model. Generally speaking, the output of the `Neck`  is used as the feature output when in inference stage.

-# Logo Recognition
-
-Logo recognition is a field that is widely used in real life, such as whether the Adidas or Nike logo appears in a photo, or whether the Starbucks or Coca-Cola logo appears on a cup. Usually, when the number of logo categories is large, the two-stage method of detection and recognition is often used. The detection module is responsible for detecting the potential logo area, and then feed the logo area to the recognition module to identify the category. The recognition module mostly adopts retrieval-based method, and sorts the similarity of the query and the gallery to obtain the predicted category. This document mainly introduces the feature learning part.
-
-## 1 Pipeline
-
-See the pipline of [feature learning](./feature_learning_en.md) for details.
-
-The config file of logo recognition: [ResNet50_ReID.yaml](../../../ppcls/configs/Logo/ResNet50_ReID.yaml).
-
-The details are as follows.
-
-### 1.1 Data Augmentation
-
-Different from classification, this part mainly uses the following methods:
-
-- `Resize` to 224.  The input image is already croped using bbox by a logo detector.
-- [AugMix](https://arxiv.org/abs/1912.02781v1)：Simulate lighting changes, camera position changes and other real scenes.
-- [RandomErasing](https://arxiv.org/pdf/1708.04896v2.pdf)：Simulate occlusion.
-
-### 1.2 Backbone
-
-Using `ResNet50` as backbone, and make the following modifications:
-
-- Last stage stride = 1, keep the size of the final output feature map to 14x14. At the cost of increasing a small amount of calculation, the ability of feature representation is greatly improved.
-- Use pretrained weights of ImageNet
-
-code：[ResNet50_last_stage_stride1](../../../ppcls/arch/backbone/variant_models/resnet_variant.py)
-
-### 1.3 Neck
-
-In order to reduce the complexity of calculating feature distance in inference, an embedding convolution layer is added, and the feature dimension is set to 512.
-
-### 1.4 Metric Learning Losses
-
-[PairwiseCosface](../../../ppcls/loss/pairwisecosface.py) , [CircleMargin](../../../ppcls/arch/gears/circlemargin.py) [1] are used. The weight ratio of two losses is 1:1.
-
-## 2 Experiment
-
-<img src="../../images/logo/logodet3k.jpg" style="zoom:50%;" />
-
-LogoDet-3K[2] dataset is used for experiments. The dataset is fully labeled, with 3000 logo categories, about 200,000 high-quality manually labeled logo objects and 158,652 images.
-
-Since the dataset is original desigined for detection task, only the cropped logo area is used in the logo recognition stage. Therefore, the labeled bbox annotations are used to crop the logo area to form the training set, eliminating the influence of the background in the recognition stage. After cropping preprocessing, the dataset was splited to 155,427 images as training sets, covering 3000 logo categories (also used as the gallery during testing), and 3225 as test sets, which were used as query sets. The cropped dataset is available [download here](https://arxiv.org/abs/2008.05359)
-
-On this data, the single model Recall@1 Acc: 89.8%.

-# Mainbody Detection
-
-The mainbody detection technology is currently a very widely used detection technology, which refers to the detect one or some mainbody objects in the picture, crop the corresponding area in the image and carry out recognition, thereby completing the entire recognition process. Mainbody detection is the first step of the recognition task, which can effectively improve the recognition accuracy.
-
-
-This tutorial will introduce the dataset and model training for mainbody detection in PaddleClas.
-
-
-## 1. Dataset
-
-The datasets we used for mainbody detection task are shown in the following table.
-
-
-| Dataset       | Image number   | Image number used in <<br>>mainbody detection   | Scenarios  | Dataset link |
-| ------------  | ------------- | -------| ------- | -------- |
-| Objects365 | 170W | 6k | General Scenarios | [link](https://www.objects365.org/overview.html) |
-| COCO2017 | 12W | 5k  | General Scenarios | [link](https://cocodataset.org/) |
-| iCartoonFace | 2k | 2k | Cartoon Face | [link](https://github.com/luxiangju-PersonAI/iCartoonFace) |
-| LogoDet-3k | 3k | 2k | Logo | [link](https://github.com/Wangjing1551/LogoDet-3K-Dataset) |
-| RPC | 3k | 3k  | Product | [link](https://rpc-dataset.github.io/) |
-
-
-In the actual training process, all datasets are mixed together. Categories of all the labeled boxes are modified to the category `foreground`, and the detection model we trained just contains one category (`foreground`).
-
-## 2. Model Selection
-
-
-There are many types of object detection methods such as the commonly used two-stage detectors (FasterRCNN series, etc.), single-stage detectors (YOLO, SSD, etc.), anchor-free detectors (FCOS, etc.) and so on.
-
-PP-YOLO is proposed by [PaddleDetection](https://github.com/PaddlePaddle/PaddleDetection). It deeply optimizes the yolov3 model from multiple perspectives such as backbone, data augmentation, regularization strategy, loss function, and post-processing. Finally, it reached the state of the art in terms of "speed-precision". Specifically, the optimization strategy is as follows.
-
-- Better backbone: ResNet50vd-DCN
-- Larger training batch size: 8 GPUs and mini-batch size as 24 on each GPU
-- [Drop Block](https://arxiv.org/abs/1810.12890)
-- [Exponential Moving Average](https://www.investopedia.com/terms/e/ema.asp)
-- [IoU Loss](https://arxiv.org/pdf/1902.09630.pdf)
-- [Grid Sensitive](https://arxiv.org/abs/2004.10934)
-- [Matrix NMS](https://arxiv.org/pdf/2003.10152.pdf)
-- [CoordConv](https://arxiv.org/abs/1807.03247)
-- [Spatial Pyramid Pooling](https://arxiv.org/abs/1406.4729)
-- Better ImageNet pretrain weights
-
-For more information about PP-YOLO, you can refer to [PP-YOLO tutorial](https://github.com/PaddlePaddle/PaddleDetection/blob/release%2F2.1/configs/ppyolo/README.md)
-
-
-In the mainbody detection task, we use `ResNet50vd-DCN` as our backbone for better performance. The config file is [ppyolov2_r50vd_dcn_365e_coco.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.1/configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml) used for the model training, in which the dagtaset path is modified to the mainbody detection dataset.
-The final inference model can be downloaded [here](https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/models/inference/ppyolov2_r50vd_dcn_mainbody_v1.0_infer.tar).
-
-
-## 3. Model training
-
-This section mainly talks about how to train your own mainbody detection model using PaddleDetection on your own dataset.
-
-### 3.1 Prepare for the environment
-
-Download PaddleDetection and install requirements。
-
-```shell
-cd <path/to/clone/PaddleDetection>
-git clone https://github.com/PaddlePaddle/PaddleDetection.git
-
-cd PaddleDetection
-# install requirements
-pip install -r requirements.txt
-```
-
-For more installation tutorials, please refer to [Installation tutorial](https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.1/docs/tutorials/INSTALL.md)
-
-### 3.2 Prepare for the dataset
-
-For customized dataset, you should convert it to COCO format. Please refer to [Customized dataset tutorial](https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.1/static/docs/tutorials/Custom_DataSet.md) to build your own dataset with COCO format.
-
-In mainbody detection task, all the objects belong to foregroud. Therefore, `category_id` of all the objects in the annotation file should be modified to 1. And the `categories` map should be modified as follows, in which just class `foregroud` is included.
-
-```json
-[{u'id': 1, u'name': u'foreground', u'supercategory': u'foreground'}]
-```
-
-### 3.3 Configuration files
-
-You can use `configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml` to train the model, mode details are as follows.
-
-<div align='center'>
-  <img src='../../images/det/PaddleDetection_config.png' width='400'/>
-</div>
-
-`ppyolov2_r50vd_dcn_365e_coco.yml` depends on other configuration files, their meanings are as follows.
-
-
-```
-coco_detection.yml：num_class of the model, and train/eval/test dataset.
-
-runtime.yml：public runtime parameters, use_gpu, save_interval, etc.
-
-optimizer_365e.yml：learning rate and optimizer.
-
-ppyolov2_r50vd_dcn.yml：model architecture.
-
-ppyolov2_reader.yml：train/eval/test reader.
-```
-
-In mainbody detection task, you need to modify `num_classes` in `datasets/coco_detection.yml` to 1 (just `foreground` is included). Dataset path should also be updated.
-
-
-### 3.4 Begin the training process
-
-
-PaddleDetection supports many ways of training process.
-
-* Training using single GPU
-
-```bash
-# not needed for windows and Mac
-export CUDA_VISIBLE_DEVICES=0
-python tools/train.py -c configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml
-```
-
-* Training using multiple GPU's
-
-```bash
-export CUDA_VISIBLE_DEVICES=0,1,2,3
-python -m paddle.distributed.launch --gpus 0,1,2,3 tools/train.py -c configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml --eval
-```
-
---eval：eval during training
-
-* (**Recommend**) Model finetune
-If you want to finetune the model on your own dataset, you can run the following command to train the model.
-
-```bash
-export CUDA_VISIBLE_DEVICES=0
-# assign pretrain_weights, load the general mainbody-detection pretrained model
-python tools/train.py -c configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml -o pretrain_weights=https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/rec/models/pretrain/ppyolov2_r50vd_dcn_mainbody_v1.0_pretrained.pdparams
-```
-
-
-* Resume training: you can use `-r` to load checkpoints and resume training.
-
-```bash
-export CUDA_VISIBLE_DEVICES=0,1,2,3
-python -m paddle.distributed.launch --gpus 0,1,2,3 tools/train.py -c configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml --eval -r output/ppyolov2_r50vd_dcn_365e_coco/10000
-```
-
-Note:
-If error `out of memory` occured, you can try to decrease `batch_size` in `ppyolov2_reader.yml`.
-
-
-### 3.5 Model prediction
-
-Use the following command to finish the prediction process.
-
-
-
-```bash
-export CUDA_VISIBLE_DEVICES=0
-python tools/infer.py -c configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml --infer_img=your_image_path.jpg --output_dir=infer_output/ --draw_threshold=0.5 -o weights=output/ppyolov2_r50vd_dcn_365e_coco/model_final
-```
-
-`--draw_threshold` is an optional parameter.
-
-### 3.6 Export model and inference.
-
-Use the following to export the inference model.
-
-```bash
-python tools/export_model.py -c configs/ppyolo/ppyolov2_r50vd_dcn_365e_coco.yml --output_dir=./inference -o weights=output/ppyolov2_r50vd_dcn_365e_coco/model_final.pdparams
-```
-
-The inference model will be saved folder `inference/ppyolov2_r50vd_dcn_365e_coco`, which contains `model.pdiparams`, `model.pdiparams.info`,`model.pdmodel` and `infer_cfg.yml`(optional for mainbody detection).
-
-* Note: Inference model name that `PaddleDetection` exports is `model.xxx`, here if you want to keep it consistent with `PaddleClas`, you can rename `model.xxx` to `inference.xxx` for subsequent inference.
-
-For more model export tutorial, please refer to [EXPORT_MODEL](https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.1/deploy/EXPORT_MODEL.md).
-
-Now you get the newest model on your own dataset. In the recognition process, you can replace the detection model path with yours. For quick start of recognition process, please refer to the [tutorial](../tutorials/quick_start_recognition_en.md).

-## Practical Server-side detection method base on RCNN
-
-### Introduction
-
-
-* In recent years, object detection tasks have attracted widespread attention. [PaddleClas](https://github.com/PaddlePaddle/PaddleClas) open-sourced the ResNet50_vd_SSLD pretrained model based on ImageNet(Top1 Acc 82.4%). And based on the pretrained model, PaddleDetection provided the PSS-DET (Practical Server-side detection) with the help of the rich operators in PaddleDetection. The inference speed can reach 61FPS on single V100 GPU when COCO mAP is 41.6%, and 20FPS when COCO mAP is 47.8%.
-
-* We take the standard `Faster RCNN ResNet50_vd FPN` as an example. The following table shows ablation study of PSS-DET.
-
-| Trick | Train scale | Test scale |  COCO mAP | Infer speed/FPS |
-|- |:-: |:-: | :-: | :-: |
-| `baseline` | 640x640 | 640x640 | 36.4% | 43.589 |
-| +`test proposal=pre/post topk 500/300` | 640x640 | 640x640 | 36.2% | 52.512 |
-| +`fpn channel=64` | 640x640 | 640x640 | 35.1% | 67.450 |
-| +`ssld pretrain` | 640x640 | 640x640 | 36.3% | 67.450 |
-| +`ciou loss` | 640x640 | 640x640 | 37.1% | 67.450 |
-| +`DCNv2` | 640x640 | 640x640 | 39.4% | 60.345 |
-| +`3x, multi-scale training` | 640x640 | 640x640 | 41.0% | 60.345 |
-| +`auto augment` | 640x640 | 640x640 | 41.4% | 60.345 |
-| +`libra sampling` | 640x640 | 640x640 | 41.6% | 60.345 |
-
-
-Based on the ablation experiments, Cascade RCNN and larger inference scale(1000x1500) are used for better performance. The final COCO mAP is 47.8%
-and the following figure shows `mAP-Speed` curves for some common detectors.

-# Product Recognition
-
-Product recogniton is now widely used . The way of shopping by taking a photo has been adopted by many people. And the unmanned settlement platform has entered the major supermarkets,  which is also supported by product recognition technology. The technology is about the process of "product detection + product identification". The product detection module is responsible for detecting potential product areas, and the product identification model is responsible for identifying the main body detected by the product detection module. The recognition module uses the retrieval method to get the similarity rank of product in database and the query image . This document mainly introduces the feature extraction part of product pictures.

-# Transfer learning in image classification
-
-Transfer learning is an important part of machine learning, which is widely used in various fields such as text and images. Here we mainly introduce transfer learning in the field of image classification, which is often called domain transfer, such as migration of the ImageNet classification model to the specified image classification task, such as flower classification.
-
-## Hyperparameter search
-
-ImageNet is the widely used dataset for image classification. A series of empirical hyperparameters have been summarized. High accuracy can be got using the hyperparameters. However, when applied in the specified dataset, the hyperparameters may not be optimal. There are two commonly used hyperparameter search methods that can be used to help us obtain better model hyperparameters.
-
-### Grid search
-
-For grid search, which is also called exhaustive search, the optimal value is determined by finding the best solution from all solutions in the search space. The method is simple and effective, but when the search space is large, it takes huge computing resource.
-
-### Bayesian search
-
-Bayesian search, which is also called Bayesian optimization, is realized by randomly selecting a group of hyperparameters in the search space. Gaussian process is used to update the hyperparameters, compute their expected mean and variance according to the performance of the previous hyperparameters. The larger the expected mean, the greater the probability of being close to the optimal solution. The larger the expected variance, the greater the uncertainty. Usually, the hyperparameter point with large expected mean is called `exporitation`, and the hyperparameter point with large variance is called `exploration`. Acquisition function is defined to balance the expected mean and variance. The currently selected hyperparameter point is viewed as the optimal position with maximum probability.
-
-According to the above two search schemes, we carry out some experiments based on fixed scheme and two search schemes on 8 open source datasets. As the experimental scheme in [1], we search for 4 hyperparameters, the search space and The experimental results are as follows:
-
-a fixed set of parameter experiments and two search schemes on 8 open source data sets. With reference to the experimental scheme of [1], we search for 4 hyperparameters, the search space and the experimental results are as follows:

-
-It takes 196 times for grid search, and takes 10 times less for Bayesian search. The baseline is trained by using ImageNet1k pretrained model based on ResNet50_vd and fixed scheme. The follow shows the experiments.

-
-- The above experiments verify that Bayesian search only reduces the accuracy by 0% to 0.4% under the condition of reducing the number of searches by about 10 times compared to grid search.
-- The search space can be expaned easily using Bayesian search.
-
-## Large-scale image classification
-
-In practical applications, due to the lack of training data, the classification model trained on the ImageNet1k data set is often used as the pretrained model for other image classification tasks. In order to further help solve practical problems, based on ResNet50_vd, Baidu open sourced a self-developed large-scale classification pretrained model, in which the training data contains 100,000 categories and 43 million pictures. The pretrained model can be downloaded as follows：[**download link**](https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/ResNet50_vd_10w_pretrained.pdparams)
-
-We conducted transfer learning experiments on 6 self-collected datasets,
-
-using a set of fixed parameters and a grid search method, in which the number of training rounds was set to 20epochs, the ResNet50_vd model was selected, and the ImageNet pre-training accuracy was 79.12%. The comparison results of the experimental data set parameters and model accuracy are as follows:

-- The above experiments verified that for fixed parameters, compared with the pretrained model on ImageNet, using the large-scale classification model as a pretrained model can help us improve the model performance on a new dataset in most cases. Parameter search can be further helpful to the model performance.

-# Vehicle Recognition
-
-This part mainly includes two parts: vehicle fine-grained classification and vehicle Reid.
-
-The goal of fine-grained classification is to recognize images belonging to multiple subordinate categories of a super-category, e.g., different species of animals/plants, different models of cars, different kinds of retail products. Obviously, fine-grained vehicle classification is to classify different sub categories of vehicles.
-
-Vehicle ReID aims to re-target vehicle images across non-overlapping camera views given a query image. It has many practical applications, such as for analyzing and managing the traffic flows in Intelligent Transport System. In this process, how to extract robust features is particularly important.
-
-In this document, the same training scheme is used to try the two application respectively.
-
-## 1 Pipeline
-
-See the pipline of [feature learning](./feature_learning_en.md) for details.
-
-The config file of Vehicle ReID: [ResNet50_ReID.yaml](../../../ppcls/configs/Vehicle/ResNet50_ReID.yaml).
-
-The config file of Vehicle fine-grained classification：[ResNet50.yaml](../../../ppcls/configs/Vehicle/ResNet50.yaml).
-
- The details are as follows.
-
-### 1.1 Data Augmentation
-
-Different from classification, this part mainly uses the following methods:
-
-- `Resize` to 224. Especially for ReID, the vehicle image is already croped using bbox by detector. So if `CenterCrop` is used, more vehicle information will be lost.
-- [AugMix](https://arxiv.org/abs/1912.02781v1)：Simulation of lighting changes, camera position changes and other real scenes.
-- [RandomErasing](https://arxiv.org/pdf/1708.04896v2.pdf)：Simulate  occlusion.
-
-### 1.2 Backbone
-
- Using `ResNet50` as  backbone, and make the following modifications:
-
-- Last stage stride = 1, keep the size of the final output feature map to 14x14. At the cost of increasing a small amount of calculation, the ability of feature expression is greatly improved.
-
-code：[ResNet50_last_stage_stride1](../../../ppcls/arch/backbone/variant_models/resnet_variant.py)
-
-### 1.3 Neck
-
-In order to reduce the complexity of calculating feature distance in inference, an embedding convolution layer is added, and the feature dimension is set to 512.
-
-### 1.4 Metric Learning Losses
-
-In vehicle ReID and vehicle fine-grained classification，[SupConLoss](../../../ppcls/loss/supconloss.py) , [ArcLoss](../../../ppcls/arch/gears/arcmargin.py) are used. The weight ratio of two losses is 1:1.
-

-
-<img src="../../images/recognition/vehicle/cars.JPG" style="zoom:50%;" />

-This method is used in VERI-Wild dataset. This dataset was captured in a large CCTV monitoring system in an unrestricted scenario for a month (30 * 24 hours). The system consists of 174 cameras, which are distributed in large area of more than 200 square kilometers. The original vehicle image set contains 12 million vehicle images. After data cleaning and labeling, 416314 images and 40671 vehicle ids are collected. [See the paper for details]( https://github.com/PKU-IMRE/VERI-Wild).

-### 2.2 Vehicle Fine-grained Classification
-
- In this applications, we use [CompCars](http://mmlab.ie.cuhk.edu.hk/datasets/comp_cars/index.html) as train dataset.
-
-![](../../images/recognition/vehicle/CompCars.png)
-
-The images in the dataset mainly come from the network and monitoring  data. The network data includes 163 automobile manufacturers and 1716  automobile models, which includes **136726** full vehicle images and **27618** partial vehicle images. The network car data includes the information of  bounding box, perspective and five  attributes (maximum speed, displacement, number of doors, number of  seats and car type) for vehicles. The monitoring data includes  **50000** front view images.
-
- It is worth noting that this dataset needs to generate labels  according to its own needs. For example, in this demo, vehicles of the  same model produced in different years are regarded as the same  category. Therefore, the total number of categories is 431.

 ### 3.3 Larger Convolution Kernels
 
 In the paper of MixNet, the author analyzes the effect of convolutional kernel size on model performance and concludes that larger convolutional kernels within a certain range can improve the performance of the model, but beyond this range will be detrimental to the model’s performance. So the author forms MixConv with split-concat paradigm combined, which can improve the performance of the model but is not conducive to inference. We experimentally summarize the role of some larger convolutional kernels at different positions that are similar to those of the SE module, and find that larger convolutional kernels display more prominent roles in the middle and tail of the network. The following table shows the effect of the position of the 5x5 convolutional kernels on the accuracy：

----
-Please refer to [Installation](install_en.md) to setup environment at first, and prepare flower102 dataset by following the instruction mentioned in the [Quick Start](quick_start_en.md).
-
-## 1. Training and Evaluation on CPU or Single GPU
-
-If training and evaluation are performed on CPU or single GPU, it is recommended to use the `tools/train.py` and `tools/eval.py`.
-For training and evaluation in multi-GPU environment on Linux, please refer to [2. Training and evaluation on Linux+GPU](#2-training-and-evaluation-on-linuxgpu).
-
-<a name="1.1"></a>
-## 1.1 Model training
-
-After preparing the configuration file, The training process can be started in the following way.
-
-```
-python tools/train.py \
-    -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-    -o Arch.pretrained=False \
-    -o Global.device=gpu
-```
-
-Among them, `-c` is used to specify the path of the configuration file, `-o` is used to specify the parameters needed to be modified or added, `-o Arch.pretrained=False` means to not using pre-trained models.
-`-o Global.device=gpu` means to use GPU for training. If you want to use the CPU for training, you need to set `Global.device` to `cpu`.
-
-
-Of course, you can also directly modify the configuration file to update the configuration. For specific configuration parameters, please refer to [Configuration Document](config_description_en.md).

-
-During training, you can view loss changes in real time through `VisualDL`,  see [VisualDL](../extension/VisualDL_en.md) for details.
-
-### 1.2 Model finetuning
-
-After configuring the configuration file, you can finetune it by loading the pretrained weights, The command is as shown below.
-
-```
-python tools/train.py \
-    -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-    -o Arch.pretrained=True \
-    -o Global.device=gpu
-```
-
-Among them, `-o Arch.pretrained` is used to set the address to load the pretrained weights. When using it, you need to replace it with your own pretrained weights' path, or you can modify the path directly in the configuration file. You can also set it into `True` to use pretrained weights that trained in ImageNet1k.
-
-We also provide a lot of pre-trained models trained on the ImageNet-1k dataset. For the model list and download address, please refer to the [model library overview](../models/models_intro_en.md).
-
-### 1.3 Resume Training
-
-If the training process is terminated for some reasons, you can also load the checkpoints to continue training.
-
-```
-python tools/train.py \
-    -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-    -o Global.checkpoints="./output/MobileNetV3_large_x1_0/epoch_5" \
-    -o Global.device=gpu
-```
-
-The configuration file does not need to be modified. You only need to add the `Global.checkpoints` parameter during training, which represents the path of the checkpoints. The parameter weights, learning rate, optimizer and other information will be loaded using this parameter.
-
-**Note**:
-
-* The `-o Global.checkpoints` parameter does not need to include the suffix of the checkpoints. The above training command will generate the checkpoints as shown below during the training process. If you want to continue training from the epoch `5`, Just set the `Global.checkpoints` to `../output/MobileNetV3_large_x1_0/epoch_5`, PaddleClas will automatically fill in the `pdopt` and `pdparams` suffixes.
-
-    ```shell
-    output
-    ├── MobileNetV3_large_x1_0
-    │   ├── best_model.pdopt
-    │   ├── best_model.pdparams
-    │   ├── best_model.pdstates
-    │   ├── epoch_1.pdopt
-    │   ├── epoch_1.pdparams
-    │   ├── epoch_1.pdstates
-        .
-        .
-        .
-    ```
-
-
-### 1.4 Model evaluation
-
-The model evaluation process can be started as follows.
-
-```bash
-python tools/eval.py \
-    -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-    -o Global.pretrained_model=./output/MobileNetV3_large_x1_0/best_model
-```
-
-The above command will use `./configs/quick_start/MobileNetV3_large_x1_0.yaml` as the configuration file to evaluate the model `./output/MobileNetV3_large_x1_0/best_model`. You can also set the evaluation by changing the parameters in the configuration file, or you can update the configuration with the `-o` parameter, as shown above.
-
-Some of the configurable evaluation parameters are described as follows:
-* `Arch.name`: Model name
-* `Global.pretrained_model`: The path of the model file to be evaluated
-
-**Note:** If the model is a dygraph type, you only need to specify the prefix of the model file when loading the model, instead of specifying the suffix, such as [1.3 Resume Training](#13-resume-training).
-
-<a name="2"></a>
-### 2. Training and evaluation on Linux+GPU
-
-If you want to run PaddleClas on Linux with GPU, it is highly recommended to use `paddle.distributed.launch` to start the model training script(`tools/train.py`) and evaluation script(`tools/eval.py`), which can start on multi-GPU environment more conveniently.
-
-### 2.1 Model training
-
-After preparing the configuration file, The training process can be started in the following way. `paddle.distributed.launch` specifies the GPU running card number by setting `gpus`:
-
-```bash
-export CUDA_VISIBLE_DEVICES=0,1,2,3
-
-python3 -m paddle.distributed.launch \
-    --gpus="0,1,2,3" \
-    tools/train.py \
-        -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml
-```
-
-The format of output log information is the same as above, see [1.1 Model training](#11-model-training) for details.
-
-### 2.2 Model finetuning
-
-After configuring the configuration file, you can finetune it by loading the pretrained weights, The command is as shown below.
-
-```
-export CUDA_VISIBLE_DEVICES=0,1,2,3
-
-python3 -m paddle.distributed.launch \
-    --gpus="0,1,2,3" \
-    tools/train.py \
-        -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-        -o Arch.pretrained=True
-```
-
-Among them, `Arch.pretrained` is set to `True` or `False`. It also can be used to set the address to load the pretrained weights. When using it, you need to replace it with your own pretrained weights' path, or you can modify the path directly in the configuration file.
-
-There contains a lot of examples of model finetuning in [Quick Start](./quick_start_en.md). You can refer to this tutorial to finetune the model on a specific dataset.
-
-<a name="model_resume"></a>
-### 2.3 Resume Training
-
-If the training process is terminated for some reasons, you can also load the checkpoints to continue training.
-
-```
-export CUDA_VISIBLE_DEVICES=0,1,2,3
-
-python3 -m paddle.distributed.launch \
-    --gpus="0,1,2,3" \
-    tools/train.py \
-        -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-        -o Global.checkpoints="./output/MobileNetV3_large_x1_0/epoch_5" \
-        -o Global.device=gpu
-```
-
-The configuration file does not need to be modified. You only need to add the `Global.checkpoints` parameter during training, which represents the path of the checkpoints. The parameter weights, learning rate, optimizer and other information will be loaded using this parameter as described in [1.3 Resume training](#13-resume-training).
-
-### 2.4 Model evaluation
-
-The model evaluation process can be started as follows.
-
-```bash
-export CUDA_VISIBLE_DEVICES=0,1,2,3
-python3 -m paddle.distributed.launch \
-    tools/eval.py \
-        -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-        -o Global.pretrained_model=./output/MobileNetV3_large_x1_0/best_model
-```
-
-About parameter description, see [1.4 Model evaluation](#14-model-evaluation) for details.
-
-<a name="model_infer"></a>
-## 3. Use the pre-trained model to predict
-After the training is completed, you can predict by using the pre-trained model obtained by the training, as follows:
-
-```python
-python3 tools/infer.py \
-    -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-    -o Infer.infer_imgs=dataset/flowers102/jpg/image_00001.jpg \
-    -o Global.pretrained_model=./output/MobileNetV3_large_x1_0/best_model
-```
-
-Among them:
-+ `Infer.infer_imgs`: The path of the image file or folder to be predicted;
-+ `Global.pretrained_model`: Weight file path, such as `./output/MobileNetV3_large_x1_0/best_model`;
-
-## 4. Use the inference model to predict
-
-PaddlePaddle supports inference using prediction engines, which will be introduced next.
-
-Firstly, you should export inference model using `tools/export_model.py`.
-
-```bash
-python3 tools/export_model.py \
-    -c ./ppcls/configs/quick_start/MobileNetV3_large_x1_0.yaml \
-    -o Global.pretrained_model=output/MobileNetV3_large_x1_0/best_model
-```
-
-Among them,  `Global.pretrained_model` parameter is used to specify the model file path that does not need to include the file suffix name.
-
-The above command will generate the model structure file (`inference.pdmodel`) and the model weight file (`inference.pdiparams`), and then the inference engine can be used for inference:
-
-Go to the deploy directory:
-
-```
-cd deploy
-```
-
-Using inference engine to inference. Because the mapping file of ImageNet1k dataset is used by default, we should set `PostProcess.Topk.class_id_map_file` into `None`.
-
-```bash
-python3 python/predict_cls.py \
-    -c configs/inference_cls.yaml \
-    -o Global.infer_imgs=../dataset/flowers102/jpg/image_00001.jpg \
-    -o Global.inference_model_dir=../inference/ \
-    -o PostProcess.Topk.class_id_map_file=None
-```
-Among them:
-+ `Global.infer_imgs`: The path of the image file to be predicted;
-+ `Global.inference_model_dir`: Model structure file path, such as `../inference/inference.pdmodel`;
-+ `Global.use_tensorrt`: Whether to use the TesorRT, default by `False`;
-+ `Global.use_gpu`: Whether to use the GPU, default by `True`
-+ `Global.enable_mkldnn`: Wheter to use `MKL-DNN`, default by `False`. It is valid when `Global.use_gpu` is `False`.
-+ `Global.use_fp16`: Whether to enable FP16, default by `False`;
-
-**Note**: If you want to use `Transformer series models`, such as `DeiT_***_384`, `ViT_***_384`, etc., please pay attention to the input size of model, and need to set `resize_short=384`, `resize=384`.
-
-If you want to evaluate the speed of the model, it is recommended to enable TensorRT to accelerate for GPU, and MKL-DNN for CPU.

-# Quick Start
----
-At first，please take a reference to [Installation Guide](./install_en.md) to prepare your environment.
-
-PaddleClas image retrieval supports the following training/evaluation environments:
-```shell
-└── CPU/Single GPU
-    ├── Linux
-    └── Windows
-```

-  * [2.3 Model Evaluation](#Model-Evaluation)
-* [3. Export Inference Model](#Export-Inference-Model)
-  
-<a name="Data-Preparation"></a>   
-## 1. Data Preparation
-
-* Go to PaddleClas directory。
-
-```bash
-## linux or mac, $path_to_PaddleClas indicates the root directory of PaddleClas, which the user needs to modify according to their real directory
-cd $path_to_PaddleClas
-```
-
-* Please go to the `dataset` catalog. In order to quickly experiment the image retrieval module of PaddleClas, the dataset we used is [CUB_200_2011](http://vision.ucsd.edu/sites/default/files/WelinderEtal10_CUB-200.pdf), which is a fine grid dataset with 200 different types of birds. Firstly, we need to download the dataset. For download, please refer to [Official Website](http://www.vision.caltech.edu/visipedia/CUB-200-2011.html).
-
-```shell
-# linux or mac
-cd dataset
-
-# Copy the downloaded data into a directory.
-cp {Data storage path}/CUB_200_2011.tgz .
-
-# Unzip
-tar -xzvf CUB_200_2011.tgz
-
-#go to `CUB_200_2011`
-cd CUB_200_2011
-```
-
-When using the dataset for image retrieval, we usually use the first 100 classes as the training set, and the last 100 classes as the testing set, so we need to process those data so as to adapt the model training of image retrival.
-
-```shell
-#Create train and test directories
-mkdir train && mkdir test
-
-#Divide data into training set with the first 100 classes and testing set with the last 100 classes.
-ls images | awk -F "." '{if(int($1)<101)print "mv images/"$0" train/"int($1)}' | sh
-ls images | awk -F "." '{if(int($1)>100)print "mv images/"$0" test/"int($1)}' | sh
-
-#Generate train_list.txt test_list.txt
-tree -r -i -f train | grep jpg | awk -F "/" '{print $0" "int($2) " "NR}' > train_list.txt
-tree -r -i -f test | grep jpg | awk -F "/" '{print $0" "int($2) " "NR}' > test_list.txt
-```
-
-
-So far, we have the training set (in the `train` catalog) and testing set (in the `test` catalog) of `CUB_200_2011`.
-After data preparation, the `train` directory of `CUB_200_2011` should be:
-
-```

-```
-
-`train_list.txt` Should be：

-```
-The separators are shown as spaces, and the meaning of those three columns of data are the directory of training set, labels of training set and unique ids of training set.  
-
-The format of testing set is the same as the one of training set.
-
-
-**Note**：
-
-* When the gallery dataset and query dataset are the same, in order to remove the first data retrieved (the retrieved images themselves do not need to be evaluated), each data needs to correspond to a unique id for subsequent evaluation of metrics such as mAP, recall@1, etc. Please refer to [Introduction to image retrieval datasets](#Introduction to image retrieval datasets) for the analysis of gallery datasets and query datasets, and [Image retrieval evaluation metrics](#Image retrieval evaluation metrics) for the evaluation of mAP, recall@1, etc.

-
-<a name="Training-and-Evaluation-on-Single-GPU"></a>  
-## 2. Single GPU-based Training and Evaluation
-
-For training and evaluation on a single GPU, the `tools/train.py` and `tools/eval.py` scripts are recommended.
-
-
-<a name="Model-Training"></a>
-### 2.1 Model Training
-
-Once you have prepared the configuration file, you can start training the image retrieval task in the following way. the method used by PaddleClas to train the image retrieval is metric learning, refering to [metric learning](#Metric-Learning) for an explanation of metric learning.
-
-
-```
-python3 tools/train.py \
-    -c ./ppcls/configs/quick_start/MobileNetV1_retrieval.yaml \
-    -o Arch.Backbone.pretrained=True \
-    -o Global.device=gpu
-```
-
- `-c` is used to specify the path to the configuration file, and `-o` is used to specify the parameters that need to be modified or added, where `-o Arch.Backbone.pretrained=True` indicates that the Backbone part uses the pre-trained model, in addition, `Arch.Backbone.pretrained` can also specify backbone.`pretrained` can also specify the address of a specific model weight file, which needs to be replaced with the path to your own pre-trained model weight file when using it. `-o Global.device=gpu` indicates that the GPU is used for training. If you want to use a CPU for training, you need to set `Global.device` to `cpu`.
-
-For more detailed training configuration, you can also modify the corresponding configuration file of the model directly. Refer to the [configuration document](config_description_en.md) for specific configuration parameters.
-
-Run the above commands to check the output log, an example is as follows:
-
-    ```
-    ...
-    [Train][Epoch 1/50][Avg]CELoss: 6.59110, TripletLossV2: 0.54044, loss: 7.13154
-    ...
-    [Eval][Epoch 1][Avg]recall1: 0.46962, recall5: 0.75608, mAP: 0.21238
-    ...
-    ```
-
-The Backbone here is MobileNetV1, if you want to use other backbone, you can rewrite the parameter `Arch.Backbone.name`, for example by adding `-o Arch.Backbone.name={other Backbone}` to the command. In addition, as the input dimension of the `Neck` section differs between models, replacing a Backbone may require rewriting the input size here in a similar way to replacing the Backbone's name.
-
-In the Training Loss section, [CELoss](../../../ppcls/loss/celoss.py) and [TripletLossV2](../../../ppcls/loss/triplet.py) is used here  with the following configuration files.
-
-```
-Loss:
-  Train:
-    - CELoss:
-        weight: 1.0
-    - TripletLossV2:
-        weight: 1.0
-        margin: 0.5
-```
-    
-The final total Loss is a weighted sum of all Losses, where weight defines the weight of a particular Loss in the final total. If you want to replace other Losses, you can also change the Loss field in the configuration file, for the currently supported Losses please refer to [Loss](../../../ppcls/loss).
-
-<a name="Resume-Training"></a>
-### 2.2 Resume Training
-
-If the training task is terminated for some reasons, it can be recovered by loading the checkpoints weights file and continue training.
-
-
-```
-python3 tools/train.py \
-    -c ./ppcls/configs/quick_start/MobileNetV1_retrieval.yaml \
-    -o Global.checkpoints="./output/RecModel/epoch_5" \
-    -o Global.device=gpu
-```
-
-There is no need to modify the configuration file, just set the `Global.checkpoints` parameter when continuing training, indicating the path to the loaded breakpoint weights file, using this parameter will load both the saved checkpoints weights and information about the learning rate, optimizer, etc.
-
-**Note**：
-
-* The `-o Global.checkpoints` parameter need not contain the suffix name of the checkpoint weights file, the above training command will generate the breakpoint weights file as shown below during training, if you want to continue training from breakpoint `5` then the `Global.checkpoints` parameter just needs to be set to `". /output/RecModel/epoch_5"` and PaddleClas will automatically supplement the suffix name.
-
-    ```shell
-    output/
-    └── RecModel
-        ├── best_model.pdopt
-        ├── best_model.pdparams
-        ├── best_model.pdstates
-        ├── epoch_1.pdopt
-        ├── epoch_1.pdparams
-        ├── epoch_1.pdstates
-        .
-        .
-        .
-    ```
-
-<a name="Model-Evaluation"></a>
-### 2.3 Model Evaluation
-
-Model evaluation can be carried out with the following commands.
-
-```bash
-python3 tools/eval.py \
-    -c ./ppcls/configs/quick_start/MobileNetV1_retrieval.yaml \
-    -o Global.pretrained_model=./output/RecModel/best_model
-```
-
-The above command will use `. /configs/quick_start/MobileNetV1_retrieval.yaml` as a configuration file to evaluate the model obtained from the above training `. /output/RecModel/best_model` for evaluation. You can also set up the evaluation by changing the parameters in the configuration file, or you can update the configuration with the `-o` parameter, as shown above.
-
-Some of the configurable evaluation parameters are introduced as follows.
-* `Arch.name`: the name of the model
-* `Global.pretrained_model`: path to the pre-trained model file of the model to be evaluated, unlike `Global.Backbone.pretrained` where the pre-trained model is the weight of the whole model, whereas `Global.Backbone.pretrained` is only the Backbone.`pretrained` is only the weight of the Backbone part. When it is time to do model evaluation, the weights of the whole model need to be loaded.
-* `Metric.Eval`: the metric to be evaluated, by default evaluates recall@1, recall@5, mAP. when you are not going to evaluate a metric, you can remove the corresponding trial marker from the configuration file; when you want to add a certain evaluation metric, you can also refer to [Metric](../../../ppcls/metric/metrics.py) section to add the relevant metric to the configuration file `Metric.Eval`.
-
-**Note：** 
-
-* When loading the model to be evaluated, the path to the model file needs to be specified, but it is not necessary to include the file suffix, PaddleClas will automatically complete the `.pdparams` suffix, e.g. [2.2 Resume Training](#Resume-Training).
-
-* Metric learning are generally not evaluated for TopkAcc.
-
-<a name="Export-Inference-Model"></a>
-## 3. Export Inference Model
-
-By exporting the inference model, PaddlePaddle supports the transformation of the trained model using prediction with inference engine.
-
-```bash
-python3 tools/export_model.py \
-    -c ./ppcls/configs/quick_start/MobileNetV1_retrieval.yaml \
-    -o Global.pretrained_model=output/RecModel/best_model \
-    -o Global.save_inference_dir=./inference
-```
-
- `Global.pretrained_model` is used to specify the model file path, which still does not need to contain the model file suffix (e.g. [2.2 Model recovery training](#Model recovery training)). When executed, it will generate the `. /inference` directory, which contains the `inference.pdiparams`, `inference.pdiparams.info`, and `inference.pdmodel` files. `Global.save_inference_dir` allows you to specify the path to export the inference model. The inference model saved here is truncated at the embedding feature level, i.e. the final output of the model is n-dimensional embedding features.
-
-The above command will generate the model structure file (`inference.pdmodel`) and the model weights file (`inference.pdiparams`), which can then be used for inference using the inference engine. The process of inference using the inference model can be found in [Predictive inference based on the Python prediction engine](@shengyu).
-
-## Basic knowledge
-
-Image retrieval refers to a query image given a specific instance (e.g. a specific target, scene, item, etc.) that contains the same instance from a database image. Unlike image classification, image retrieval solves an open set problem where the training set may not contain the class of the image being recognised. The overall process of image retrieval is: firstly, the images are represented in a suitable feature vector, secondly, a nearest neighbour search is performed on these image feature vectors using Euclidean or Cosine distances to find similar images in the base, and finally, some post-processing techniques can be used to fine-tune the retrieval results and determine information such as the category of the image being recognised. Therefore, the key to determining the performance of an image retrieval algorithm lies in the goodness of the feature vectors corresponding to the images.

-<a name="Metric-Learning"></a>
-- Metric Learning
-
-Metric learning studies how to learn a distance function on a particular task so that the distance function can help nearest-neighbour based algorithms (kNN, k-means, etc.) to achieve better performance. Deep Metric Learning is a method of metric learning that aims to learn a mapping from the original features to a low-dimensional dense vector space (embedding space) such that similar objects on the embedding space are closer together using commonly used distance functions (Euclidean distance, cosine distance, etc.) ) on the embedding space, while the distances between objects of different classes are relatively close to each other. Deep metric learning has achieved very successful applications in the field of computer vision, such as face recognition, commodity recognition, image retrieval, pedestrian re-identification, etc.

-  - Training Dataset: used to train the model so that it can learn the image features of the collection.
-  - Gallery Dataset: used to provide the gallery data for the image retrieval task. The gallery dataset can be the same as the training set or the test set, or different.
-  - Test Set (Query Dataset): used to test the goodness of the model, usually each test image in the test set is extracted with features, and then matched with the features of the underlying data to obtain recognition results, and then the metrics of the whole test set are calculated based on the recognition results.

-# Image Classification
----
-
-Image Classification is a fundamental task that classifies the image by semantic information and assigns it to a specific label. Image Classification is the foundation of Computer Vision tasks, such as object detection, image segmentation, object tracking and behavior analysis. Image Classification has comprehensive applications, including face recognition and smart video analysis in the security and protection field, traffic scenario recognition in the traffic field, image retrieval and electronic photo album classification in the internet industry, and image recognition in the medical industry.  
-
-Generally speaking, Image Classification attempts to comprehend an entire image as a whole by feature engineering and assigns labels by a classifier. Hence, how to extract the features of image is the essential part. Before we have deep learning, the most used classification method is the Bag of Words model. However, Image Classification based on deep learning can learn the hierarchical feature description by supervised and unsupervised learning, replacing the manually image feature selection. Recently, Convolution Neural Network in deep learning has an awesome performance in the image field. CNN uses the pixel information as the input to get the all information to the maximum extent. Additionally, since the model uses convolution to extract features, the classification result is the output. Thus, this kind of end-to-end method achieves ideal performance and is applied widely. 
-
-Image Classification is a very basic but important field in the subject of computer vision. Its research results have always influenced the development of computer vision and even deep learning. Image classification has many sub-fields, such as multi-label image classification and fine-grained image classification. Here is only a brief description of single-label image classification.
-
-
-## 1 Dataset Introduction
-
-### 1.1 ImageNet-1k
-
-The ImageNet project is a large-scale visual database for the research of visual object recognition software. More than 14 million images have been annotated manually to point out objects in the picture in this project, and at least more than 1 million images provide borders. ImageNet-1k is a subset of the ImageNet dataset, which contains 1000 categories. The training set contains 1281167 image data, and the validation set contains 50,000 image data. Since 2010, the ImageNet project has held an image classification competition every year, which is the ImageNet Large-scale Visual Recognition Challenge (ILSVRC). The dataset used in the challenge is ImageNet-1k. So far, ImageNet-1k has become one of the most important data sets for the development of computer vision, and it promotes the development of the entire computer vision. The initialization models of many computer vision downstream tasks are based on the weights trained on this dataset.
-
-### 1.2 CIFAR-10/CIFAR-100
-
-The CIFAR-10 data set consists of 60,000 color images in 10 categories, with an image resolution of 32x32, and each category has 6000 images, including 5000 in the training set and 1000 in the validation set. 10 different classes represent airplanes, cars, birds, cats, deer, dogs, frogs, horses, ships and trucks. The CIFAR-100 data set is an extension of CIFAR-10. It consists of 60,000 color images in 100 classes, with an image resolution of 32x32, and each class has 600 images, including 500 in the training set and 100 in the validation set. Researchers can try different algorithms quickly because these two data sets are small in scale. These two data sets are also commonly used data sets for testing the quality of models in the image classification field.
-
-## 2 Image Classification Process
-
-The prepared training data is preprocessed by the corresponding data and then passed through the image classification model. The output of the model and the real label are used in a cross-entropy loss function. This loss function describes the convergence direction of the model.  Traverse all the image data input model, do the corresponding gradient descent for the final loss function through some optimizers, return the gradient information to the model, update the weight of the model, and traverse the data repeatedly. Finally, an image classification model can be obtained.
-
-### 2.1 Data and its preprocessing
-
-The quality and quantity of data often determine the performance of a model. In the field of image classification, data includes images and labels. In most cases, labeled data is scarce, so the amount of data is difficult to reach the level of saturation of the model. In order to enable the model to learn more image features, a lot of image transformation or data augmentation is required before the image enters the model, so as to ensure the diversity of input image data. Ultimately ensure that the model has better generalization capabilities. PaddleClas provides standard image transformation for training ImageNet-1k, and also provides 8 data augmentation methods. For related codes, please refer to[data preprocess](../../../ppcls/data/preprocess)，The configuration file refer to [Data Augmentation Configuration File](../../../ppcls/configs/ImageNet/DataAugment).
-
-### 2.2 Prepare the model
-
-After the data is determined, the model often determines the upper limit of the final accuracy. In the field of image classification, classic models emerge in an endless stream. PaddleClas provides 35 series and a total of 164 ImageNet pre-trained models. For specific accuracy, speed and other indicators, please refer to[Backbone network introduction](../models).
-
-### 2.3 Train the model
-
-After preparing the data and model, you can start training the model and update the parameters of the model. After many iterations, a trained model can finally be obtained for image classification tasks. The training process of image classification requires a lot of experience and involves the setting of many hyperparameters. PaddleClas provides a series of [training tuning methods](../models/Tricks_en.md), which can quickly help you obtain a high-precision model.
-
-### 2.4 Evaluate the model
-
-After a model is trained, the evaluation results of the model on the validation set can determine the performance of the model. The evaluation index is generally Top1-Acc or Top5-Acc. The higher the index, the better the model performance.
-

-## 3 Main Algorithms Introduction 
-
-- LeNet: Yan LeCun et al. first applied convolutional neural networks to image classification tasks in the 1990s, and creatively proposed LeNet, which achieved great success in handwritten digit recognition tasks.
-
-- AlexNet: Alex Krizhevsky et al. proposed AlexNet in 2012 and applied it to ImageNet, and won the 2012 ImageNet classification competition. Since then, deep learning has become popular
-
-- VGG: Simonyan and Zisserman proposed the VGG network structure in 2014. This network structure uses a smaller convolution kernel to stack the entire network, achieving better performance in ImageNet classification, it provides new ideas for the subsequent network structure design.
-
-- GoogLeNet: Christian Szegedy et al. proposed GoogLeNet in 2014. This network uses a multi-branch structure and a global average pooling layer (GAP). While maintaining the accuracy of the model, the amount of model storage and calculation is greatly reduced. The network won the 2014 ImageNet classification competition.
-
-- ResNet: Kaiming He et al. proposed ResNet in 2015, which deepened the depth of the network by introducing a residual module. In the end, the network reduced the recognition error rate of ImageNet classification to 3.6%, which exceeded the recognition accuracy of normal human eyes for the first time.
-
-- DenseNet: Huang Gao et al. proposed DenseNet in 2017. The network designed a denser connected block and achieved higher performance with a smaller amount of parameters.
-
-- EfficientNet: Mingxing Tan et al. proposed EfficientNet in 2019. This network balances the width of the network, the depth of the network, and the resolution of the input image. With the same FLOPS and parameters, the accuracy reaches the state-of-the-art.
