Webrsvd: Randomized Singular Value Decomposition. Low-rank matrix decompositions are fundamental tools and widely used for data analysis, dimension reduction, and data … WebDimensionality reduction using truncated SVD (aka LSA). This transformer performs linear dimensionality reduction by means of truncated singular value decomposition (SVD). Contrary to PCA, this estimator does not center the data before computing the singular value decomposition. This means it can work with sparse matrices efficiently.
