Matrix factorization

Last but not least, the matrix factorization algorithm provides a powerful and easy-to-use algorithm for providing recommendations. This algorithm is tailored to problems where historical data is available and the problem to solve is predicting a selection from that data, such as movie or music predictions. Netflix's movie suggestion system uses a form of matrix factorization for its suggestions about what movies it thinks you will enjoy. 

We will cover matrix factorization in detail in Chapter 7, Matrix Factorization Model.
