**SVD** refers to **singular value decomposition** in linear algebra. However, in the field of collaborative filtering, the term "SVD" often refers to matrix factorization.

## SVD in Math

The traditional SVD can also be used as collaborative filtering algorithm.
It is also named **latent semantic indexing** (**LSI**) in information retrieval.

- SVD++ is a generalization of matrix factorization to make use of implicit feedback.
