Description

Adding exclude_items list when using BPR.recommend or recommend_all

So, I have a need where I must exclude certain list of items for recommendation when using recommend or recommend_all. Mainly due to time constraint.

How do I implement this?

I though about doing top_k * 3, then filtering on my own side but that method is very ugly and might not even work, maybe all top_k * 3 recommendation might be in exclude list.

Research direction
Investigate the BPR recommendation code to see if exclude items parameter exists. If not, check the recommend and recommend all methods for filtering mechanisms. Consider adding an exclude list parameter as a new feature.
