Splet05. avg. 2024 · SVD is the decomposition of a matrix A into 3 matrices – U, S, and V. S is the diagonal matrix of singular values. Think of singular values as the importance values of different features in the matrix. The rank of a matrix is a measure of the unique information stored in a matrix. Higher the rank, more the information.
