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