Code questions

Hi :)
I have a small question in the code.
I do not know why it has"-1" in the below part.

STAMP/model/STAMP_cikm.py

Line 218 in c0233b6

_out = tmp_out[s]-1

_out = tmp_out[s]-1

Thank you!

大概是输出的label是从0开始计数的吧

About your questions, because the index 0 in item dictionary is for padding and it shouldn't be used to computing a recommendation score, you can see we use embe_dict[1:] to calculate the recommendation score for each item . So when evaluating the results, the true index for each target item should minus 1 to get its corresponding score in the score list,that's why you see _out = tmp_out[s]-1

For example, the index of first item in embedding dictionary is 1, but the index of its recommendation score in score list is 0.
