In Proceedings of 28th International Joint Conference on Artificial Intelligence (IJCAI 2019)

Operating environment

please use pip install -r requirements.txt to setup the operating environment in python3.6.

Download dataset and preprocess

Download dataset

  1. Download Dataset Ad Display/Click Data on Taobao.com
  2. Extract the files into the raw_data directory

Data preprocessing

  1. run 0_gen_sampled_data.py, sample the data by user
  2. run 1_gen_sessions.py, generate historical session sequence for each user

Training and Evaluation

Train DIN model

  1. run 2_gen_din_input.py,generate input data
  2. run train_din.py

Train DIEN model

  1. run 2_gen_dien_input.py,generate input data(It may take a long time to sample negative samples.)
  2. run train_dien.py

Train DSIN model

  1. run 2_gen_dsin_input.py,generate input data
  2. run train_dsin.py

    The loss of DSIN with bias_encoding=True may be NaN sometimes on Advertising Dataset and it remains a confusing problem since it never occurs in the production environment.We will work on it and also appreciate your help.
