The paper evaluates performance using HR, MRR, and NDCG. Could you please elaborate on how the ground truth for the Next-POI recommendation task is defined, and how the data are split into training and testing sets to prevent temporal information leakage? In most cases, many prepossessing procedures might be applied to the dataset before building the model. Thus, there is no really ground truth for my case. However, we can still compare the performance of different models to know how well my proposed method work.
