# DeepInterestNetwork
Deep Interest Network for Click-Through Rate Prediction

## Introduction
This is an implementation of the paper [Deep Interest Network for Click-Through Rate Prediction](https://arxiv.org/abs/1706.06978) Guorui Zhou, Chengru Song, Xiaoqiang Zhu, Han Zhu, Ying Fan, Na Mou, Xiao Ma, Yanghui Yan, Xingya Dai, Junqi Jin, Han Li, Kun Gai

## Requirements
* Python >= 2.6.1
* NumPy >= 1.12.1
* Pandas >= 0.20.1
* TensorFlow >= 1.4.0 (Probably earlier version should work too, though I didn't test it)
* GPU with memory >= 10G

## Download dataset and preprocess
* Step 1: Download the amazon product dataset of electronics category, which has 498,196 products and 7,824,482 records, and extract it to `raw_data/` folder.
```sh
mkdir raw_data/;
cd utils;
bash 0_download_raw.sh;
```
* Step 2: Convert raw data to pandas dataframe, and remap categorical id.
```sh
python 1_convert_pd.py;
python 2_remap_id.py
```

## Training and Evaluation
This implementation not only contains the DIN method, but also provides all the competitors' method, including Wide&Deep, PNN, DeepFM. The training procedures of all method is as follows:
* Step 1: Choose a method and enter the folder.
```
cd din;
```
Alternatively, you could also run other competitors's methods directly by `cd deepFM` `cd pnn` `cd wide_deep`,
and follow the same instructions below.

* Step 2: Building the dataset adapted to current method.
```
python build_dataset.py

We put a processed data 'dataset.pkl' in DeepInterestNetwork/din. Considering the GitHub's file size limit of 100.00 MB, we split it into 3 file aa ab ac.

cat aa ab ac > dataset.pkl


```
* Step 3: Start training and evaluating using default arguments in background mode. 
```
python train.py >log.txt 2>&1 &
```
* Step 4: Check training and evaluating progress.
```
tail -f log.txt
tensorboard --logdir=save_path
```

## Dice
There is also an implementation of Dice in folder 'din', you can try dice following the code annotation in `din/model.py` or replacing model.py with model\_dice.py
