Analysis of perturbations of singular values in concatenated matrices

UDC 512.5 Concatenating matrices is a common technique for uncovering shared structures in the data by using singular-valued decomposition (SVD) and low-rank approximations. The main analyzed question is to determine the relationship between the singular-valued spectrum of the concatenated matrix an...
