Abstract: In one example in accordance with the present disclosure, a system comprises a computing node. The computing node comprises: a memory, and a processor to: execute a database in the memory, and invoke, with the database, singular value decomposition (SVD) on a data set. To invoke SVD, the processor may sparsify, with the database, the data set to produce a sparse data set, iteratively decompose, with the database, the data set to produce a set of eigenvalues, solve, with the database a linear system to produce a set of eigenvectors, and multiply, with the database, the eigenvectors with the data set to produce a data set of reduced dimension.
