meaning of paramter "NUM_OF_NEGATIVE_PER_IMPLICIT"
Hi, I have two questions.
- I'm a little bit confused with the paramter "NUM_OF_NEGATIVE_PER_IMPLICIT". Is it used in bootstrap sampling procedure? Would you please point out the related formula in paper "Rendle S, Freudenthaler C, Gantner Z, et al. BPR: Bayesianpersonalized ranking from implicit feedback[C]//Proceedings of the 25th Conference on Uncertainty in Artificial Intelligence".
- Do you fix the bug in distributed version of BPR in scala? Thanks a lot.
hey @kiminh the parameter is simply the number of negative samples we use per positive example. We haven't yet, have you? If so, please open a PR! 👍
