Collaborative Filtering for Implicit Feedback Datasets

Alternating Least Squares

Vs. SVD as A Latent Factor Model

기존의 Singular Value Decomposition 모델은 explicit feedback 을 가정하고 학습을 진행했지만, 이 논문에서 제안한 방식은 implicit feedback 을 가정하고 학습을 진행한다.

Issue

these algorithms are just suitable for the MF with simple manual confidence weights, which lacks flexible and may create empirical bias.
