Identifiability of Kronecker-structured Dictionaries for Tensor Data

Abstract

This paper derives sufficient conditions for reliable recovery of coordinate dictionaries comprising a Kroneckerstructured dictionary that is used for representing Kth-order tensor data. Tensor observations are generated by a Kroneckerstructured dictionary and sparse coefficient tensors that follow the separable sparsity model. This work provides sufficient… (More)
