<p align="center">
<img align="center" src="doc/imgs/rec-overview-en.png">
<p>
- Recommendation system helps users quickly find useful and interesting information from massive data.
- Recommendation system is also a silver bullet to attract users, retain users, increase users' stickness or conversionn.
> Who can better use the recommendation system, who can gain more advantage in the fierce competition.
>
> At the same time, there are many problems in the process of using the recommendation system, such as: huge data, complex model, inefficient distributed training, and so on.
<h2 align="center">What is PaddleRec ?</h2>

<h2 align="center">Getting Started</h2>
### Environmental requirements
* Python 2.7/ 3.5 / 3.6 / 3.7
* PaddlePaddle >= 1.7.2
* operating system: Windows/Mac/Linux
> Linux is recommended for distributed training
### Installation
1. **Install by pip**
```bash
python -m pip install paddle-rec
```
> This method will download and install `paddlepaddle-v1.7.2-cpu`. If `PaddlePaddle` can not be installed automatically，You need to install `PaddlePaddle` manually，and then install `PaddleRec` again：
> - Download [PaddlePaddle](https://pypi.org/project/paddlepaddle/1.7.2/#files) and install by pip.
> - Install `PaddlePaddle` by pip，`python -m pip install paddlepaddle==1.7.2 -i https://mirror.baidu.com/pypi/simple`
> - Other installation problems can be raised in [Paddle Issue](https://github.com/PaddlePaddle/Paddle/issues) or [PaddleRec Issue](https://github.com/PaddlePaddle/PaddleRec/issues)
2. **Install by source code**
- Install PaddlePaddle
```shell
python -m pip install paddlepaddle==1.7.2 -i https://mirror.baidu.com/pypi/simple
```
- Install PaddleRec by source code
```
git clone https://github.com/PaddlePaddle/PaddleRec/
cd PaddleRec
python setup.py install
```
- Install PaddleRec-GPU
After installing `PaddleRec`，please install the appropriate version of `paddlepaddle-gpu` according to your environment (CUDA / cudnn)，refer to the installation tutorial [Installation Manuals](https://www.paddlepaddle.org.cn/documentation/docs/en/install/index_en.html)
<h2 align="center">Quick Start</h2>
We take the `dnn` algorithm as an example to get start of `PaddleRec`, and we take 100 pieces of training data from [Criteo Dataset](https://www.kaggle.com/c/criteo-display-ad-challenge/):
```bash
# Training with cpu
git clone https://github.com/PaddlePaddle/PaddleRec.git paddle-rec
cd paddle-rec
python -m paddlerec.run -m models/rank/dnn/config.yaml
```

# PaddleRec 自定义数据集及Reader
用户自定义数据集及配置异步Reader，需要关注以下几个步骤：
* [数据集整理](#数据集整理)
* [在模型组网中加入输入占位符](#在模型组网中加入输入占位符)
* [Reader实现](#Reader的实现)
* [在yaml文件中配置Reader](#在yaml文件中配置reader)
我们以CTR-DNN模型为例，给出了从数据整理，变量定义，Reader写法，调试的完整历程。
* [数据及Reader示例-DNN](#数据及Reader示例-DNN)
## 数据集整理
PaddleRec支持模型自定义数据集。
关于数据的tips：
1. 数据量：
PaddleRec面向大规模数据设计，可以轻松支持亿级的数据读取，工业级的数据读写api：`dataset`在搜索、推荐、信息流等业务得到了充分打磨。
2. 文件类型:
支持任意直接可读的文本数据，`dataset`同时支持`.gz`格式的文本压缩数据，无需额外代码，可直接读取。数据样本应以`\n`为标志，按行组织。
3. 文件存放位置：
文件通常存放在训练节点本地，但同时，`dataset`支持使用`hadoop`远程读取数据，数据无需下载到本地，为dataset配置hadoop相关账户及地址即可。
4. 数据类型
Reader处理的是以行为单位的`string`数据，喂入网络的数据需要转为`int`,`float`的数值数据，不支持`string`喂入网络，不建议明文保存及处理训练数据。
5. Tips
Dataset模式下，训练线程与数据读取线程的关系强相关，为了多线程充分利用，`强烈建议将文件合理的拆为多个小文件`，尤其是在分布式训练场景下，可以均衡各个节点的数据量，同时加快数据的下载速度。
## 在模型组网中加入输入占位符
Reader读取文件后，产出的数据喂入网络，需要有占位符进行接收。占位符在Paddle中使用`fluid.data`或`fluid.layers.data`进行定义。`data`的定义可以参考[fluid.data](https://www.paddlepaddle.org.cn/documentation/docs/zh/api_cn/fluid_cn/data_cn.html#data)以及[fluid.layers.data](https://www.paddlepaddle.org.cn/documentation/docs/zh/api_cn/layers_cn/data_cn.html#data)。
假如您希望输入三个数据，分别是维度32的数据A，维度变长的稀疏数据B，以及一个一维的标签数据C，并希望梯度可以经过该变量向前传递，则示例如下：
数据A的定义：
```python
var_a = fluid.data(name='A', shape= [-1, 32], dtype='float32')
```
数据B的定义，变长数据的使用可以参考[LoDTensor](https://www.paddlepaddle.org.cn/documentation/docs/zh/beginners_guide/basic_concept/lod_tensor.html#cn-user-guide-lod-tensor)：
```python
var_b = fluid.data(name='B', shape=[-1, 1], lod_level=1, dtype='int64')
```
数据C的定义：
```python
var_c = fluid.data(name='C', shape=[-1, 1], dtype='int32')
var_c.stop_gradient = False
```
当我们完成以上三个数据的定义后，在PaddleRec的模型定义中，还需将其加入model基类成员变量`self._data_var`
```python
self._data_var.append(var_a)
self._data_var.append(var_b)
self._data_var.append(var_c)
```
至此，我们完成了在组网中定义输入数据的工作。
## Reader的实现
### Reader的实现范式
Reader的逻辑需要一个单独的python文件进行描述。我们试写一个`test_reader.py`，实现的具体流程如下：
1. 首先我们需要引入Reader基类
```python
from paddlerec.core.reader import ReaderBase
```
2. 创建一个子类，继承Reader的基类，训练所需Reader命名为`TrainerReader`
```python
class TrainerReader(ReaderBase):
def init(self):
pass
def generator_sample(self, line):
pass
```
3. 在`init(self)`函数中声明一些在数据读取中会用到的变量，必要时可以在`config.yaml`文件中配置变量，利用`env.get_global_env()`拿到。
比如，我们希望从yaml文件中读取一个数据预处理变量`avg=10`，目的是将数据A的数据缩小10倍，可以这样实现：
首先更改yaml文件，在某个space下加入该变量
```yaml
...
train:
reader:
avg: 10
...
```
再更改Reader的init函数
```python
from paddlerec.core.utils import envs
class TrainerReader(Reader):
def init(self):
self.avg = envs.get_global_env("avg", None, "train.reader")
def generator_sample(self, line):
pass
```
4. 继承并实现基类中的`generate_sample(self, line)`函数，逐行读取数据。
- 该函数应返回一个可以迭代的reader方法(带有yield的函数不再是一个普通的函数，而是一个生成器generator，成为了可以迭代的对象，等价于一个数组、链表、文件、字符串etc.)
- 在这个可以迭代的函数中，如示例代码中的`def reader()`，我们定义数据读取的逻辑。以行为单位的数据进行截取，转换及预处理。
- 最后，我们需要将数据整理为特定的格式，才能够被PaddleRec的Reader正确读取，并灌入的训练的网络中。简单来说，数据的输出顺序与我们在网络中创建的`inputs`必须是严格一一对应的，并转换为类似字典的形式。
示例： 假设数据ABC在文本数据中，每行以这样的形式存储：
```shell
0.1,0.2,0.3...3.0,3.1,3.2 \t 99999,99998,99997 \t 1 \n
```
则示例代码如下：
```python
from paddlerec.core.utils import envs
class TrainerReader(Reader):
def init(self):
self.avg = envs.get_global_env("avg", None, "train.reader")
def generator_sample(self, line):
def reader(self, line):
# 先分割 '\n'， 再以 '\t'为标志分割为list
variables = (line.strip('\n')).split('\t')
# A是第一个元素，并且每个数据之间使用','分割
var_a = variables[0].split(',') # list
var_a = [float(i) / self.avg for i in var_a] # 将str数据转换为float
# B是第二个元素，同样以 ',' 分割
var_b = variables[1].split(',') # list
var_b = [int(i) for i in var_b] # 将str数据转换为int
# C是第三个元素, 只有一个元素，没有分割符
var_c = variables[2]
var_c = int(var_c) # 将str数据转换为int
var_c = [var_c] # 将单独的数据元素置入list中
# 将数据与数据名结合，组织为dict的形式
# 如下，output形式为{ A: var_a, B: var_b, C: var_c}
variable_name = ['A', 'B', 'C']
output = zip(variable_name, [var_a] + [var_b] + [var_c])
# 将数据输出，使用yield方法，将该函数变为了一个可迭代的对象
yield output
```
至此，我们完成了Reader的实现。
### 在yaml文件中配置Reader
在模型的yaml配置文件中，主要的修改是三个，如下
```yaml
reader:
batch_size: 2
class: "{workspace}/reader.py"
train_data_path: "{workspace}/data/train_data"
reader_debug_mode: False
```
batch_size: 顾名思义，是小批量训练时的样本大小
class: 运行改模型所需reader的路径
train_data_path: 训练数据所在文件夹
reader_debug_mode: 测试reader语法，及输出是否符合预期的debug模式的开关
## 数据及Reader示例-DNN
Reader代码来源于[criteo_reader.py](../models/rank/criteo_reader.py), 组网代码来源于[model.py](../models/rank/dnn/model.py)
### Criteo数据集格式
CTR-DNN训练及测试数据集选用[Display Advertising Challenge](https://www.kaggle.com/c/criteo-display-ad-challenge/)所用的Criteo数据集。该数据集包括两部分：训练集和测试集。训练集包含一段时间内Criteo的部分流量，测试集则对应训练数据后一天的广告点击流量。
每一行数据格式如下所示：
```bash
<label> <integer feature 1> ... <integer feature 13> <categorical feature 1> ... <categorical feature 26>
```
其中```<label>```表示广告是否被点击，点击用1表示，未点击用0表示。```<integer feature>```代表数值特征（连续特征），共有13个连续特征。```<categorical feature>```代表分类特征（离散特征），共有26个离散特征。相邻两个特征用```\t```分隔，缺失特征用空格表示。测试集中```<label>```特征已被移除。
### Criteo数据集的预处理
数据预处理共包括两步：
- 将原始训练集按9:1划分为训练集和验证集
- 数值特征（连续特征）需进行归一化处理，但需要注意的是，对每一个特征```<integer feature i>```，归一化时用到的最大值并不是用全局最大值，而是取排序后95%位置处的特征值作为最大值，同时保留极值。
### CTR网络输入的定义
正如前所述，Criteo数据集中，分为连续数据与离散（稀疏）数据，所以整体而言，CTR-DNN模型的数据输入层包括三个，分别是：`dense_input`用于输入连续数据，维度由超参数`dense_feature_dim`指定，数据类型是归一化后的浮点型数据。`sparse_input_ids`用于记录离散数据，在Criteo数据集中，共有26个slot，所以我们创建了名为`C1~C26`的26个稀疏参数输入，并设置`lod_level=1`，代表其为变长数据，数据类型为整数；最后是每条样本的`label`，代表了是否被点击，数据类型是整数，0代表负样例，1代表正样例。
在Paddle中数据输入的声明使用`paddle.fluid.layers.data()`，会创建指定类型的占位符，数据IO会依据此定义进行数据的输入。
稀疏参数输入的定义:
```python
def sparse_inputs():
ids = envs.get_global_env("hyper_parameters.sparse_inputs_slots", None)
sparse_input_ids = [
fluid.layers.data(name="S" + str(i),
shape=[1],
lod_level=1,
dtype="int64") for i in range(1, ids)
]
return sparse_input_ids
```
稠密参数输入的定义：
```python
def dense_input():
dim = envs.get_global_env("hyper_parameters.dense_input_dim", None)
dense_input_var = fluid.layers.data(name="D",
shape=[dim],
dtype="float32")
return dense_input_var
```
标签的定义：
```python
def label_input():
label = fluid.layers.data(name="click", shape=[1], dtype="int64")
return label
```
组合起来，正确的声明他们：
```python
self.sparse_inputs = sparse_inputs()
self.dense_input = dense_input()
self.label_input = label_input()
self._data_var.append(self.dense_input)
for input in self.sparse_inputs:
self._data_var.append(input)
self._data_var.append(self.label_input)
```
### Criteo Reader写法
```python
# 引入PaddleRec的Reader基类
from paddlerec.core.reader import ReaderBase
# 引入PaddleRec的读取yaml配置文件的方法
from paddlerec.core.utils import envs
# 定义TrainReader，需要继承 paddlerec.core.reader.Reader
class Reader(ReaderBase)::
# 数据预处理逻辑，继承自基类
# 如果无需处理， 使用pass跳过该函数的执行
def init(self):
self.cont_min_ = [0, -3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
self.cont_max_ = [20, 600, 100, 50, 64000, 500, 100, 50, 500, 10, 10, 10, 50]
self.cont_diff_ = [20, 603, 100, 50, 64000, 500, 100, 50, 500, 10, 10, 10, 50]
self.hash_dim_ = envs.get_global_env("hyper_parameters.sparse_feature_number", None, "train.model")
self.continuous_range_ = range(1, 14)
self.categorical_range_ = range(14, 40)
# 读取数据方法，继承自基类
# 实现可以迭代的reader函数，逐行处理数据
def generate_sample(self, line):
"""
Read the data line by line and process it as a dictionary
"""
def reader():
"""
This function needs to be implemented by the user, based on data format
"""
features = line.rstrip('\n').split('\t')
dense_feature = []
sparse_feature = []
for idx in self.continuous_range_:
if features[idx] == "":
dense_feature.append(0.0)
else:
dense_feature.append(
(float(features[idx]) - self.cont_min_[idx - 1]) /
self.cont_diff_[idx - 1])
for idx in self.categorical_range_:
sparse_feature.append(
[hash(str(idx) + features[idx]) % self.hash_dim_])
label = [int(features[0])]
feature_name = ["D"]
for idx in self.categorical_range_:
feature_name.append("S" + str(idx - 13))
feature_name.append("label")
yield zip(feature_name, [dense_feature] + sparse_feature + [label])
return reader
```
### 调试Reader
在Linux下运行时，默认启动`Dataset`模式，在Win/Mac下运行时，默认启动`Dataloader`模式。
通过在`config.yaml`中添加或修改`reader_debug_mode=True`打开debug模式，只会结合组网运行reader的部分，读取10条样本，并print，方便您观察格式是否符合预期或隐藏bug。
```yaml
reader:
batch_size: 2
class: "{workspace}/../criteo_reader.py"
train_data_path: "{workspace}/data/train"
reader_debug_mode: True
```
修改后，使用paddlerec.run执行该修改后的yaml文件，可以观察输出。
```bash
python -m paddlerec.run -m ./models/rank/dnn/config.yaml -e single
```
### Dataset调试
dataset输出的数据格式如下：
` dense_input:size ; dense_input:value ; sparse_input:size ; sparse_input:value ; ... ; sparse_input:size ; sparse_input:value ; label:size ; label:value `
基本规律是对于每个变量，会先输出其维度大小，再输出其具体值。
直接debug `criteo_reader`理想的输出为(截取了一个片段)：
```bash
...
13 0.0 0.00497512437811 0.05 0.08 0.207421875 0.028 0.35 0.08 0.082 0.0 0.4 0.0 0.08 1 737395 1 210498 1 903564 1 286224 1 286835 1 906818 1 90
6116 1 67180 1 27346 1 51086 1 142177 1 95024 1 157883 1 873363 1 600281 1 812592 1 228085 1 35900 1 880474 1 984402 1 100885 1 26235 1 410878 1 798162 1 499868 1 306163 1 0
...
```
可以看到首先输出的是13维的dense参数，随后是分立的sparse参数，最后一个是1维的label，数值为0，输出符合预期。
>使用Dataset的一些注意事项
> - Dataset的基本原理：将数据print到缓存，再由C++端的代码实现读取，因此，我们不能在dataset的读取代码中，加入与数据读取无关的print信息，会导致C++端拿到错误的数据信息。
> - dataset目前只支持在`unbuntu`及`CentOS`等标准Linux环境下使用，在`Windows`及`Mac`下使用时，会产生预料之外的错误，请知悉。
### DataLoader调试
dataloader的输出格式为`list: [ list[var_1], list[var_2], ... , list[var_3]]`，每条样本的数据会被放在一个 **list[list]** 中，list[0]为第一个variable。
直接debug `criteo_reader`理想的输出为(截取了一个片段)：
```bash
...
[[0.0, 0.004975124378109453, 0.05, 0.08, 0.207421875, 0.028, 0.35, 0.08, 0.082, 0.0, 0.4, 0.0, 0.08], [560746], [902436], [262029], [182633], [368411], [735166], [321120], [39572], [185732], [140298], [926671], [81559], [461249], [728372], [915018], [907965], [818961], [850958], [311492], [980340], [254960], [175041], [524857], [764893], [526288], [220126], [0]]
...
```
可以看到首先输出的是13维的dense参数的list，随后是分立的sparse参数，各自在一个list中，最后一个是1维的label的list，数值为0，输出符合预期。

# 如何给模型增加Metric
## PaddleRec Metric使用示例
```
from paddlerec.core.model import ModelBase
from paddlerec.core.metrics import RecallK
class Model(ModelBase):
def __init__(self, config):
ModelBase.__init__(self, config)
def net(self, inputs, is_infer=False):
...
acc = RecallK(input=logits, label=label, k=20)
self._metrics["Train_P@20"] = acc
```
## Metric类
### 成员变量
> _global_metric_state_vars（dict),
字典类型，用以存储metric计算过程中需要的中间状态变量。一般情况下，这些中间状态需要是Persistable=True的变量，所以会在模型保存的时候也会被保存下来。因此infer阶段需手动将这些中间状态值清零，进而保证预测结果的正确性。
### 成员函数
> clear(self, scope):
从scope中将self._global_metric_state_vars中的状态值全清零。该函数一般用在**infer**阶段开始的时候。用以保证预测指标的正确性。
> calc_global_metrics(self, fleet, scope=None):
将self._global_metric_state_vars中的状态值在所有训练节点上做all_reduce操作，进而下一步调用_calculate()函数计算全局指标。若fleet=None，则all_reduce的结果为自己本身，即单机全局指标计算。
> get_result(self): 返回训练过程中需要fetch，并定期打印至屏幕的变量。返回类型为dict。
## Metrics
### AUC
> AUC(input ,label, curve='ROC', num_thresholds=2**12 - 1, topk=1, slide_steps=1)
Auc，全称Area Under the Curve(AUC)，该层根据前向输出和标签计算AUC，在二分类(binary classification)估计中广泛使用。在二分类(binary classification)中广泛使用。相关定义参考 https://en.wikipedia.org/wiki/Receiver_operating_characteristic#Area_under_the_curve 。
#### 参数
- **input(Tensor|LoDTensor)**: 数据类型为float32，float64。浮点二维变量。输入为网络的预测值。shape为[batch_size, 2]。
- **label(Tensor|LoDTensor)**: 数据类型为int64，int32。输入为数据集的标签。shape为[batch_size, 1]。
- **curve(str)**: 曲线类型，可以为 ROC 或 PR，默认 ROC。
- **num_thresholds(int)**: 将roc曲线离散化时使用的临界值数。默认200。
- **topk(int)**: 取topk的输出值用于计算。
- **slide_steps(int)**: - 当计算batch auc时，不仅用当前步也用于先前步。slide_steps=1，表示用当前步；slide_steps = 3表示用当前步和前两步；slide_steps = 0，则用所有步。
#### 返回值
该指标训练过程中定期的变量有两个：
- **AUC**: 整体AUC值
- **BATCH_AUC**：当前batch的AUC值
### PrecisionRecall
> PrecisionRecall(input, label, class_num)
计算precison, recall, f1。
#### 参数
- **input(Tensor|LoDTensor)**: 数据类型为float32,float64。输入为网络的预测值。shape为[batch_size, class_num]
- **label(Tensor|LoDTensor)**: 数据类型为int32。输入为数据集的标签。shape为 [batch_size, 1]
- **class_num(int)**: 类别个数。
#### 返回值
- **[TP FP TN FN]**: 形状为[class_num, 4]的变量，用以表征每种类型的TP，FP，TN和FN值。TP=true positive, FP=false positive, TN=true negative, FN=false negative。若需计算每种类型的precison, recall，f1, 则可根据如下公式进行计算：
precision = TP / (TP + FP); recall = TP = TP / (TP + FN); F1 = 2 * precision * recall / (precision + recall)。
- **precision_recall_f1**: 形状为[6]，分别代表[macro_avg_precision, macro_avg_recall, macro_avg_f1, micro_avg_precision, micro_avg_recall, micro_avg_f1]，这里macro代表先计算每种类型的准确率，召回率，F1，然后求平均。micro代表先计算所有类型的整体TP，TN， FP, FN等中间值，然后在计算准确率，召回率，F1.
### RecallK
> RecallK(input, label, k=20)
TopK的召回准确率，对于任意一条样本来说，若前top_k个分类结果中包含正确分类标签，则视为正样本。
#### 参数
- **input(Tensor|LoDTensor)**: 数据类型为float32,float64。输入为网络的预测值。shape为[batch_size, class_dim]
- **label(Tensor|LoDTensor)**: 数据类型为int64，int32。输入为数据集的标签。shape为 [batch_size, 1]
- **k(int)**: 取每个类别中top_k个预测值用于计算召回准确率。
#### 返回值
- **InsCnt**：样本总数
- **RecallCnt**: topk可以正确被召回的样本数
- **Acc(Recall@k)**: RecallCnt/InsCnt，即Topk召回准确率。
## PairWise_PN
> PosNegRatio(pos_score, neg_score)
正逆序指标，一般用在输入是pairwise的模型中。例如输入既包含正样本，也包含负样本，模型需要去学习最大化正负样本打分的差异。
#### 参数
- **pos_score(Tensor|LoDTensor）**: 正样本的打分，数据类型为float32，float64。浮点二维变量，值的范围为[0,1]。
- **neg_score(Tensor|LoDTensor)**：负样本的打分。数据类型为float32，float64。浮点二维变量，值的范围为[0,1]。
#### 返回值
- **RightCnt**: pos_score > neg_score的样本数
- **WrongCnt**: pos_score <= neg_score的样本数
- **PN**: (RightCnt + 1.0) / (WrongCnt + 1.0), 正逆序，+1.0是为了避免除0错误。
### Customized_Metric
如果你需要在自定义metric，那么你需要按如下步骤操作：
1. 继承paddlerec.core.Metric，定义你的MyMetric类。
2. 在MyMetric的构造函数中，自定义Metric组网，声明self._global_metric_state_vars私有变量。
3. 定义_calculate(global_metrics)，全局指标计算。该函数的输入globla_metrics，存储了self._global_metric_state_vars中所有中间状态变量的全局统计值。最终结果以str格式返回。
自定义Metric模版如下，你可以参考注释，或paddlerec.core.metrics下已经实现的precision_recall， auc, pairwise_pn， recall_k等指标的计算方式，自定义自己的Metric类。
```
from paddlerec.core.Metric import Metric
class MyMetric(Metric):
def __init__(self):
# 1. 自定义Metric组网
** 1. your code **
# 2. 设置中间状态字典
self._global_metric_state_vars = dict()
** 2. your code **
def get_result(self):
# 3. 定义训练过程中需要打印的变量，以字典格式返回
self. _metrics = dict()
** 3. your code **
def _calculate(self, global_metrics):
# 4. 全局指标计算，global_metrics为字典类型，存储了self._global_metric_state_vars中所有中间状态变量的全局统计值。返回格式为str。
** your code **

# match-pyramid文本匹配模型
## 介绍
在许多自然语言处理任务中，匹配两个文本是一个基本问题。一种有效的方法是从单词，短语和句子中提取有意义的匹配模式以产生匹配分数。受卷积神经网络在图像识别中的成功启发，神经元可以根据提取的基本视觉模式（例如定向的边角和边角）捕获许多复杂的模式，所以我们尝试将文本匹配建模为图像识别问题。本模型对齐原作者庞亮开源的tensorflow代码：https://github.com/pl8787/MatchPyramid-TensorFlow/blob/master/model/model_mp.py， 实现了下述论文中提出的Match-Pyramid模型：
```text
@inproceedings{Pang L , Lan Y , Guo J , et al. Text Matching as Image Recognition[J]. 2016.,
title={Text Matching as Image Recognition},
author={Liang Pang, Yanyan Lan, Jiafeng Guo, Jun Xu, Shengxian Wan, Xueqi Cheng},
year={2016}
}
```
## 数据准备
训练及测试数据集选用Letor07数据集和 embed_wiki-pdc_d50_norm 词向量初始化embedding层。
该数据集包括：
1.词典文件：我们将每个单词映射得到一个唯一的编号wid，并将此映射保存在单词词典文件中。例如：word_dict.txt
2.语料库文件：我们使用字符串标识符的值表示一个句子的编号。第二个数字表示句子的长度。例如：qid_query.txt和docid_doc.txt
3.关系文件：关系文件被用来存储两个句子之间的关系，如query 和document之间的关系。例如：relation.train.fold1.txt, relation.test.fold1.txt
4.嵌入层文件：我们将预训练的词向量存储在嵌入文件中。例如：embed_wiki-pdc_d50_norm
## 数据下载和预处理
本文提供了数据集的下载以及一键生成训练和测试数据的预处理脚本，您可以直接一键运行:bash data_process.sh
执行该脚本，会从国内源的服务器上下载Letor07数据集，删除掉data文件夹中原有的relation.test.fold1.txt和relation.train.fold1.txt，并将完整的数据集解压到data文件夹。随后运行 process.py 将全量训练数据放置于`./data/train`，全量测试数据放置于`./data/test`。并生成用于初始化embedding层的embedding.npy文件
执行该脚本的理想输出为：
```
bash data_process.sh

## 一键训练并测试评估
本文提供了一键执行训练，测试和评估的脚本，您可以直接一键运行：bash run.sh
执行该脚本后，会执行python -m paddlerec.run -m ./config.yaml 命令开始训练并测试模型，将测试的结果保存到result.txt文件，最后通过执行eval.py进行评估得到数据的map指标
执行该脚本的理想输出为：
```
..............test.................
13651
336
('map=', 0.420878322843591)
```
## 每个文件的作用
paddlerec可以：
通过config.yaml规定模型的参数
通过model.py规定模型的组网
使用train_reader.py读取训练集中的数据
使用test_reader.py读取测试集中的数据。
本文额外提供：
data_process.sh用来一键处理数据
run.sh用来一键启动训练，直接得出测试结果
eval.py通过保存的测试结果，计算map指标
如需详细了解paddlerec的使用方法请参考https://github.com/PaddlePaddle/PaddleRec/blob/master/README_CN.md 页面下方的教程。

## 模型简介
不同于CTR预估问题，CVR预估面临两个关键问题：
1. **Sample Selection Bias (SSB)** 转化是在点击之后才“有可能”发生的动作，传统CVR模型通常以点击数据为训练集，其中点击未转化为负例，点击并转化为正例。但是训练好的模型实际使用时，则是对整个空间的样本进行预估，而非只对点击样本进行预估。即是说，训练数据与实际要预测的数据来自不同分布，这个偏差对模型的泛化能力构成了很大挑战。
2. **Data Sparsity (DS)** 作为CVR训练数据的点击样本远小于CTR预估训练使用的曝光样本。
ESMM是发表在 SIGIR’2018 的论文[《Entire Space Multi-Task Model: An Effective Approach for Estimating Post-Click Conversion Rate》]( https://arxiv.org/abs/1804.07931 )文章基于 Multi-Task Learning 的思路，提出一种新的CVR预估模型——ESMM，有效解决了真实场景中CVR预估面临的数据稀疏以及样本选择偏差这两个关键问题
本项目在paddlepaddle上实现ESMM的网络结构，并在开源数据集[Ali-CCP：Alibaba Click and Conversion Prediction]( https://tianchi.aliyun.com/datalab/dataSet.html?dataId=408 )上验证模型效果, 本模型配置默认使用demo数据集，若进行精度验证，请参考[论文复现](https://github.com/PaddlePaddle/PaddleRec/tree/master/models/multitask/esmm#论文复现)部分。

## 模型简介
多任务模型通过学习不同任务的联系和差异，可提高每个任务的学习效率和质量。多任务学习的的框架广泛采用shared-bottom的结构，不同任务间共用底部的隐层。这种结构本质上可以减少过拟合的风险，但是效果上可能受到任务差异和数据分布带来的影响。 论文[《Modeling Task Relationships in Multi-task Learning with Multi-gate Mixture-of-Experts》]( https://www.kdd.org/kdd2018/accepted-papers/view/modeling-task-relationships-in-multi-task-learning-with-multi-gate-mixture- )中提出了一个Multi-gate Mixture-of-Experts(MMOE)的多任务学习结构。MMOE模型刻画了任务相关性，基于共享表示来学习特定任务的函数，避免了明显增加参数的缺点。
我们在Paddlepaddle定义MMOE的网络结构，在开源数据集Census-income Data上验证模型效果，两个任务的auc分别为：
1.income
> max_mmoe_test_auc_income：0.94937
>
> mean_mmoe_test_auc_income：0.94465
2.marital
> max_mmoe_test_auc_marital：0.99419
>
> mean_mmoe_test_auc_marital：0.99324
若进行精度验证，请参考[论文复现](https://github.com/PaddlePaddle/PaddleRec/tree/master/models/multitask/mmoe#论文复现)部分。
