WebDec 6, 2024 · by kindsonthegenius December 6, 2024. Singular Value Decomposition (SVD) is a dimensionality reduction technique similar to PCA but more effective than PCA. It is considered as factorization of a data matrix into three matrices. Given a rectangular matrix A which is an n x p matrix, the SVD theorem shows that this matrix can be represented as: WebThe singular values are always real numbers. If the matrix A is a real matrix, then U and V are also real. To understand how to solve for SVD, let’s take the example of the matrix that …
