Hello, these metrics are calculated as described in the document https://bigscity-libcity-docs.readthedocs.io/en/latest/user_guide/evaluator/traj_loc_pred.html. You can look up "Recall and Precision at k for Recommender Systems" to understand how these metrics are computed. In essence, you treat the actual next location visited by the user as the item they purchased, and the model's top k predicted locations as the top k recommended items.
