v0.5.0

Breaking API Changes

The API for implicit has substantially changed in v0.5.0 - and any code written for the previous API will need to be rewritten:

• Change model.fit to take a user_items sparse matrix #484
• Return numpy arrays from recommend methods #482
• Don't require empty rows in user_items and item_users parameters #526
• Unify API for rank_items/recommend/recommend_all #489

Performance Improvements

• Speedup evaluation by using batch recommend functions #520
• Use FAISS for GPU inference #506
• Multithreaded speedups for CPU models #517
• Use thrust::binary_search to verify negative samples on GPU #524
• Release GIL on GPU calls #528

New Features

• Add incremental retraining support for ALS models #527
• Add filtering for similar_items and similar_users #488
• Add support for recalculate_users/items on the GPU #515
• Add methods for converting MF models to/from gpu #521
• Add a tutorial notebook for the lastfm example #529
