Link Prediction via Convex Nonnegative Matrix Factorization on Multiscale Blocks
Low rank matrices approximations have been used in link prediction for networks, which are usually global optimal methods and lack of using the local information. The block structure is a significant local feature of matrices: entities in the same block have similar values, which implies that links...
