3. 创建一个子类，继承dataset的基类，基类有多种选择，如果是多种数据类型混合，并且需要转化为数值进行预处理的，建议使用`MultiSlotDataGenerator`；若已经完成了预处理并保存为数据文件，可以直接以`string`的方式进行读取，使用`MultiSlotStringDataGenerator`，能够进一步加速。在示例代码，我们继承并实现了名为`CriteoDataset`的dataset子类，使用`MultiSlotDataGenerator`方法。
4. 继承并实现基类中的`generate_sample`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.)
5. 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。例如对以行为单位的数据进行截取，转换及预处理。
6. 最后，我们需要将数据整理为特定的格式，才能够被dataset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。在示例代码中，我们使用`zip`的方法将参数名与数值构成的元组组成了一个list，并将其yield输出。如果展开来看，我们输出的数据形如`[('dense_feature',[value]),('C1',[value]),('C2',[value]),...,('C26',[value]),('label',[value])]`
6. 最后，我们需要将数据整理为特定的格式，才能够被dataset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。在示例代码中，我们将数据整理成`click:value dense_feature:value ... dense_feature:value 1:value ... 26:value`的格式。用print输出是因为我们在run.sh中将结果重定向到slot_train_data等文件中，由模型直接读取。在用户自定义使用时，可以使用`zip`的方法将参数名与数值构成的元组组成了一个list，并将其yield输出，并在config.yaml中的data_converter参数指定reader的路径。

## 模型组网
### 数据输入声明
正如数据准备章节所介绍，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.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。
```python
dense_input = fluid.data(name="dense_input",
shape=[-1, args.dense_feature_dim],
dtype="float32")
sparse_input_ids = [
fluid.data(name="C" + str(i),
shape=[-1, 1],
lod_level=1,
dtype="int64") for i in range(1, 27)
]
label = fluid.data(name="label", shape=[-1, 1], dtype="int64")
inputs = [dense_input] + sparse_input_ids + [label]
```

### CTR-DNN模型组网
CTR-DNN模型的组网比较直观，本质是一个二分类任务，代码参考`model.py`。模型主要组成是一个`Embedding`层，三个`FC`层，以及相应的分类任务的loss计算和auc计算。
CTR-DNN模型的组网比较直观，本质是一个二分类任务，代码参考`model.py`。模型主要组成是一个`Embedding`层，四个`FC`层，以及相应的分类任务的loss计算和auc计算。
#### Embedding层
首先介绍Embedding层的搭建方式：`Embedding`层的输入是`sparse_input`，shape由超参的`sparse_feature_dim`和`embedding_size`定义。需要特别解释的是`is_sparse`参数，当我们指定`is_sprase=True`后，计算图会将该参数视为稀疏参数，反向更新以及分布式通信时，都以稀疏的方式进行，会极大的提升运行效率，同时保证效果一致。
首先介绍Embedding层的搭建方式：`Embedding`层的输入是`sparse_input`，由超参的`sparse_feature_number`和`sparse_feature_dimshape`定义。需要特别解释的是`is_sparse`参数，当我们指定`is_sprase=True`后，计算图会将该参数视为稀疏参数，反向更新以及分布式通信时，都以稀疏的方式进行，会极大的提升运行效率，同时保证效果一致。
各个稀疏的输入通过Embedding层后，将其合并起来，置于一个list内，以方便进行concat的操作。
```python
def embedding_layer(input):
return fluid.layers.embedding(
if self.distributed_embedding:
emb = fluid.contrib.layers.sparse_embedding(
input=input,
size=[self.sparse_feature_number, self.sparse_feature_dim],
param_attr=fluid.ParamAttr(
name="SparseFeatFactors",
initializer=fluid.initializer.Uniform()))
else:
emb = fluid.layers.embedding(
input=input,
is_sparse=True,
size=[args.sparse_feature_dim,
args.embedding_size],
is_distributed=self.is_distributed,
size=[self.sparse_feature_number, self.sparse_feature_dim],
param_attr=fluid.ParamAttr(
name="SparseFeatFactors",
initializer=fluid.initializer.Uniform()),
)
name="SparseFeatFactors",
initializer=fluid.initializer.Uniform()))
emb_sum = fluid.layers.sequence_pool(input=emb, pool_type='sum')
return emb_sum
sparse_embed_seq = list(map(embedding_layer, inputs[1:-1])) # [C1~C26]
sparse_embed_seq = list(map(embedding_layer, self.sparse_inputs)) # [C1~C26]
```
#### FC层
将离散数据通过embedding查表得到的值，与连续数据的输入进行`concat`操作，合为一个整体输入，作为全链接层的原始输入。我们共设计了3层FC，每层FC的输出维度都为400，每层FC都后接一个`relu`激活函数，每层FC的初始化方式为符合正态分布的随机初始化，标准差与上一层的输出维度的平方根成反比。
将离散数据通过embedding查表得到的值，与连续数据的输入进行`concat`操作，合为一个整体输入，作为全链接层的原始输入。我们共设计了4层FC，每层FC的输出维度由超参`fc_sizes`指定，每层FC都后接一个`relu`激活函数，每层FC的初始化方式为符合正态分布的随机初始化，标准差与上一层的输出维度的平方根成反比。
```python
concated = fluid.layers.concat(sparse_embed_seq + inputs[0:1], axis=1)
fc1 = fluid.layers.fc(
input=concated,
size=400,
act="relu",
param_attr=fluid.ParamAttr(initializer=fluid.initializer.Normal(
scale=1 / math.sqrt(concated.shape[1]))),
)
fc2 = fluid.layers.fc(
input=fc1,
size=400,
act="relu",
param_attr=fluid.ParamAttr(initializer=fluid.initializer.Normal(
scale=1 / math.sqrt(fc1.shape[1]))),
)
fc3 = fluid.layers.fc(
input=fc2,
size=400,
act="relu",
param_attr=fluid.ParamAttr(initializer=fluid.initializer.Normal(
scale=1 / math.sqrt(fc2.shape[1]))),
)
concated = fluid.layers.concat(
sparse_embed_seq + [self.dense_input], axis=1)
fcs = [concated]
hidden_layers = envs.get_global_env("hyper_parameters.fc_sizes")
for size in hidden_layers:
output = fluid.layers.fc(
input=fcs[-1],
size=size,
act='relu',
param_attr=fluid.ParamAttr(
initializer=fluid.initializer.Normal(
scale=1.0 / math.sqrt(fcs[-1].shape[1]))))
fcs.append(output)
```
#### Loss及Auc计算
- 预测的结果通过一个输出shape为2的FC层给出，该FC层的激活函数是softmax，会给出每条样本分属于正负样本的概率。
- 每条样本的损失由交叉熵给出，交叉熵的输入维度为[batch_size,2]，数据类型为float，label的输入维度为[batch_size,1]，数据类型为int。
- 该batch的损失`avg_cost`是各条样本的损失之和
- 我们同时还会计算预测的auc，auc的结果由`fluid.layers.auc()`给出，该层的返回值有三个，分别是全局auc: `auc_var`，当前batch的auc: `batch_auc_var`，以及auc_states: `auc_states`，auc_states包含了`batch_stat_pos, batch_stat_neg, stat_pos, stat_neg`信息。`batch_auc`我们取近20个batch的平均，由参数`slide_steps=20`指定，roc曲线的离散化的临界数值设置为4096，由`num_thresholds=2**12`指定。
- 我们同时还会计算预测的auc，auc的结果由`fluid.layers.auc()`给出，该层的返回值有三个，分别是从第一个batch累计到当前batch的全局auc: `auc`，最近几个batch的auc: `batch_auc`，以及auc_states: `_`，auc_states包含了`batch_stat_pos, batch_stat_neg, stat_pos, stat_neg`信息。`batch_auc`我们取近20个batch的平均，由参数`slide_steps=20`指定，roc曲线的离散化的临界数值设置为4096，由`num_thresholds=2**12`指定。
```
predict = fluid.layers.fc(
input=fc3,
size=2,
act="softmax",
param_attr=fluid.ParamAttr(initializer=fluid.initializer.Normal(
scale=1 / math.sqrt(fc3.shape[1]))),
)
cost = fluid.layers.cross_entropy(input=predict, label=inputs[-1])
avg_cost = fluid.layers.reduce_sum(cost)
accuracy = fluid.layers.accuracy(input=predict, label=inputs[-1])
auc_var, batch_auc_var, auc_states = fluid.layers.auc(
input=predict,
label=inputs[-1],
num_thresholds=2**12,
slide_steps=20)
```
input=fcs[-1],
size=2,
act="softmax",
param_attr=fluid.ParamAttr(initializer=fluid.initializer.Normal(
scale=1 / math.sqrt(fcs[-1].shape[1]))))
完成上述组网后，我们最终可以通过训练拿到`avg_cost`与`auc`两个重要指标。
self.predict = predict
auc, batch_auc, _ = fluid.layers.auc(input=self.predict,label=self.label_input,
num_thresholds=2**12,
slide_steps=20)
cost = fluid.layers.cross_entropy(
input=self.predict, label=self.label_input)
avg_cost = fluid.layers.reduce_mean(cost)
```
完成上述组网后，我们最终可以通过训练拿到`BATCH_AUC`与`auc`两个重要指标。

## 模型简介
GRU4REC模型的介绍可以参阅论文[Session-based Recommendations with Recurrent Neural Networks](https://arxiv.org/abs/1511.06939)。
论文的贡献在于首次将RNN（GRU）运用于session-based推荐，相比传统的KNN和矩阵分解，效果有明显的提升。
论文的核心思想是在一个session中，用户点击一系列item的行为看做一个序列，用来训练RNN模型。预测阶段，给定已知的点击序列作为输入，预测下一个可能点击的item。
session-based推荐应用场景非常广泛，比如用户的商品浏览、新闻点击、地点签到等序列数据。
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](#论文复现)部分。
本项目支持功能
训练：单机CPU、单机单卡GPU、本地模拟参数服务器训练、增量训练，配置请参考 [启动训练](https://github.com/PaddlePaddle/PaddleRec/blob/master/doc/train.md)
预测：单机CPU、单机单卡GPU；配置请参考[PaddleRec 离线预测](https://github.com/PaddlePaddle/PaddleRec/blob/master/doc/predict.md)
## 数据处理
本示例中数据处理共包含三步：
- Step1: 原始数据数据集下载
```
cd data/
python download.py
```
- Step2: 数据预处理及格式转换。
1. 以session_id为key合并原始数据集，得到每个session的日期，及顺序点击列表。
2. 过滤掉长度为1的session；过滤掉点击次数小于5的items。
3. 训练集、测试集划分。原始数据集里最新日期七天内的作为训练集，更早之前的数据作为测试集。
```
python preprocess.py
python convert_format.py
```
这一步之后，会在data/目录下得到两个文件，rsc15_train_tr_paddle.txt为原始训练文件，rsc15_test_paddle.txt为原始测试文件。格式如下所示：
```
214536502 214536500 214536506 214577561
214662742 214662742 214825110 214757390 214757407 214551617
214716935 214774687 214832672
214836765 214706482
214701242 214826623
214826835 214826715
214838855 214838855
214576500 214576500 214576500

214717867 21471786
```
- Step3: 生成字典并整理数据路径。这一步会根据训练和测试文件生成字典和对应的paddle输入文件，并将训练文件统一放在data/all_train目录下，测试文件统一放在data/all_test目录下。
```
mkdir raw_train_data && mkdir raw_test_data
mv rsc15_train_tr_paddle.txt raw_train_data/ && mv rsc15_test_paddle.txt raw_test_data/
mkdir all_train && mkdir all_test
python text2paddle.py raw_train_data/ raw_test_data/ all_train all_test vocab.txt
```
方便起见，我们提供了一键式数据生成脚本：
```
sh data_prepare.sh
```

## 论文复现
用原论文的完整数据复现论文效果需要在config.yaml修改超参：
- batch_size: 修改config.yaml中dataset_train数据集的batch_size为500。
- epochs: 修改config.yaml中runner的epochs为10。
- 数据源：修改config.yaml中dataset_train数据集的data_path为"{workspace}/data/all_train"，dataset_test数据集的data_path为"{workspace}/data/all_test"。
使用gpu训练10轮 测试结果为
epoch | 测试recall@20 | 速度(s)
-- | -- | --
1 | 0.6406 | 6003
2 | 0.6727 | 6007
3 | 0.6831 | 6108
4 | 0.6885 | 6025
5 | 0.6913 | 6019
6 | 0.6931 | 6011
7 | 0.6952 | 6015
8 | 0.6968 | 6076
9 | 0.6972 | 6076
10 | 0.6987| 6009
修改后运行方案：修改config.yaml中的'workspace'为config.yaml的目录位置，执行
```
python -m paddlerec.run -m /home/your/dir/config.yaml #调试模式 直接指定本地config的绝对路径
```
