MetaHIN

Source code for KDD 2020 paper "Meta-learning on Heterogeneous Information Networks for Cold-start Recommendation"

Requirements

• Python 3.6.9
• PyTorch 1.4.0
• My operating system is Ubuntu 16.04.1 with one GPU (GeForce RTX) and CPU (Intel Xeon W-2133)
• Detailed requirements

Datasets

We have uploaded the original data of DBook, Movielens and Yelp in the data/ folder.

The processed data of DBook and Movielens can be downloaded from Google Drive and BaiduYun (Extraction code: ened).

The processed data of Yelp can be generate by the code data/yelp/YelpProcessor.ipynb.
