WebJul 31, 2006 · Abstract The singular value decomposition (SVD) has been extensively used in engineering and statistical applications. This method was originally discovered by Eckart and Young in [ Psychometrika, 1 (1936), pp. 211--218], where they considered the problem of low-rank approximation to a matrix.

WebThe Eckart-Young Theorem provides the means to do so, by defining [[X y] + [X˜ y˜]] as the “best” rank-napproximation to [X y]. Dropping the last (smallest) singular value of [X y] eliminates the least amount of information from the data and ensures a unique solution (assuming σ n+1 is not very close to σ n).
