As the netflix prize competition has demonstrated, matrix factorization models are superior to classic nearest neighbor techniques for producing product recommendations, allowing the incorporation of additional information such as implicit feedback, temporal effects, and confidence levels.

Matrix factorization methods when a user gives feed back to a certain movie they saw (say they can rate from one to five), this collection of feedback can be represented in a form of a matrix. Collaborative filtering using matrix factorization — simplified r ecommendation systems are one of the most successful and fascinating applications of machine learning.
