# Vision transformer Detection

## Introduction

- [Context Autoencoder for Self-Supervised Representation Learning](https://arxiv.org/abs/2202.03026)  
- [Benchmarking Detection Transfer Learning with Vision Transformers](https://arxiv.org/pdf/2111.11429.pdf)  

Object detection is a central downstream task used to
test if pre-trained network parameters confer benefits, such
as improved accuracy or training speed. The complexity
of object detection methods can make this benchmarking
non-trivial when new architectures, such as Vision Transformer (ViT) models, arrive.

## Model Zoo

| Backbone | Pretrained | Model | Scheduler | Images/GPU  | Box AP | Config | Download |
|:------:|:--------:|:--------------:|:--------------:|:--------------:|:------:|:------:|:--------:|
| ViT-base | CAE | Cascade RCNN  | 1x | 1 | -- | [config](./cascade_rcnn_vit_base_hrfpn_cae_1x_coco.yml) | [coming soon]() |
| ViT-large | CAE | Cascade RCNN  | 1x | 1 | -- | [config](./cascade_rcnn_vit_large_hrfpn_cae_1x_coco.yml) | [coming soon]() |

**Notes:**
- Model is trained on COCO train2017 dataset and evaluated on val2017 results of `mAP(IoU=0.5:0.95)`.
- Base model is trained on 8x32G V100 GPU, large model on 8x80G A100.
