Title:

New Results on Tensor Computation: Completion, Decomposition, and Invariance Properties

 

Speaker:

Shuzhong Zhang

Department of Industrial and Systems Engineering

University of Minnesota

 

Abstract:

This talk will touch upon two topics in tensor computations. The first one relates to a new matricization approach, resulting in lower and upper approximations for the CP-rank. In this part, theoretical properties of the new ranks (to be called the M-ranks) will be discussed, with applications to solve the low CP-rank tensor completion problem. The second topic establishes the equivalence between a tensor and its Tucker core, in terms of the CP-rank, the Schatten norms, and the Z-eigenvalues of tensors. A new computational scheme is proposed based on the invariance properties. This talk is based on the joint research with Bo Jiang, Shiqian Ma, and Fan Yang.
