Hello, can you tell me how the "relational ratio in test set" in the paper Rechorus is calculated? thank you very much

THUwangcy commented 2 years ago

Assuming we have 10 interactions in the test set, together with 10 corresponding historical sequences, we examine whether each testing item i_t is relational to any item j in the historical sequence (e.g., <j, also_buy, i_t> holds). If 3 testing items can be found relational to at least one item in the historical sequence, the relational ratio in test set is 30%.
