Alternating Least Squares Method for Collaborative Filtering. An Informal DefinitionRecommender systems is a family of methods that enable filtering through large observation and information space in order to provide recommendations in the information space that user does not have any observation, where the information space is all of the available items that user could choose or select and observation space is what user experienced or observed so far.
