Environments

• python 3.6
• PyTorch (version: 0.4.0)
• numpy (version: 1.15.0)
• scipy (version: 1.1.0)
• sklearn (version: 0.19.1)

Dataset

In our experiments, the Foursquare and Yelp datasets are from http://spatialkeyword.sce.ntu.edu.sg/eval-vldb17/. And the Gowalla dataset is from https://snap.stanford.edu/data/loc-gowalla.html (if you need the data after preprocessing, please send me an email).

Example to run the code

Data preprocessing:

Run the cal_poi_pairwise_relation.py to calculate the pairwise relations between locations, which will be stored in ./data/Foursquare/.

python cal_poi_pairwise_relation.py	

Train and evaluate the model (you are strongly recommended to run the program on a machine with GPU):

python run.py
