SDM: Sequential Deep Matching Model for Online Large-scale Recommender System

New Released Code!!!

Thanks to the DeepMatch Group members for providing doc and code.

Demo Code

Code (Python2.7, TF1.4) of the sequential deep matching (SDM) model for recommender system at Taobao. Current version only contains the core code of our model. The processes of data processing and evaluation are executed on our internal cloud platform ODPS.

Paper

Here is the arxiv link (accepted by CIKM 2019)

Dataset

JD Dataset: raw data, train and test data in the paper (tfrecord). The schema of raw data is shown in data/sample_data/.

Disclaimer

This is an implementation on experiment of offline JD dataset rather than the online official version. There may be differences between results reported in the paper and the released one, because the former one is achieved in distribution tensorflow on our internal deep learning platform PAI.
