Requirements

  • Python 3.x
  • Paddlepaddle 2.x / Pytorch >= 1.7

Data Format

For check-in data, you need to format the hometown and out-of-town check-ins of users in two respective files following:

{user id}\t{timestamp}\t{poi id}\t{poi tag}

For POI distance data, please format as:

{poi id 1}\t{poi id 2}\t{distance}

Also, we provided a toy data generator to help you run the code. Run:

python generate_toy_data.py

to generate the toy data.

Run Our Model

Simply run the following command to train:

cd ./PaddlePaddle
python run.py --ori_data {...} --dst_data {...} --dist_data {...} ---save_path {...} --mode train

Then, test the performance with a trained TrainOR model:

cd ./PaddlePaddle
python run.py --ori_data {...} --dst_data {...} --dist_data {...} --test_path {...} --mode test
