Did you know?
Web˙p j (W))1=p is the Schatten p-norm for matrices, where ˙j(W) is the jth largest singular value of W. When used as a regularizer, the overlapped Schatten 1-norm penalizes all modes of W to be jointly low-rank. It is related to the overlapped group regularization [see 13, 16] in a sense that the same object W appears repeatedly in the norm.
