The code implementation does not match the original paper

[Bohao Wang]

The function _sample_negative in data.py appears to be incorrect. It currently utilizes ratings to generate negative samples, resulting in the exclusion of test items for each user from the negative samples. But the test items should be treated as negative samples in training set.

@yihong-chen I created a full request, which is able to produce comparable results to the one reported in the paper. Have a look.
