The Schatten-p quasi-norm (0<p<1) is usually used to replace the standard nuclear norm in order to approximate the rank function more accurately. However, existing Schatten-p quasi-norm minimization algorithms involve singular value decomposition (SVD) or eigenvalue decomposition (EVD) in each iteration, and thus may become very slow and impractical for large-scale problems. In this paper, we first define two tractable Schatten quasi-norms, i.e., Frobenius/nuclear hybrid and bi-nucleardoi:10.1609/aaai.v30i1.10266 fatcat:3xl7yxje25gp7blsptwynpb6ve
