A Probabilistic Reformulation of Memory-Based Collaborative Filtering

Rocío Cañamares, Pablo Castells
2017 Proceedings of the 40th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '17  
We develop a probabilistic formulation giving rise to a formal version of heuristic nearest-neighbor (kNN) collaborative filtering.  ...  Moreover, a natural explanation arises for the bias of kNN towards recommending popular items.  ...  The nearest-neighbor collaborative filtering strategy (also known as memory-based, or heuristic) is one among hundreds of solutions to the recommendation problem.  ...
