Fast Revealing of Mode Ranks of Tensor in Canonical Form

Author(s)

Abstract

Considering the problem of mode ranks revealing of $d$-dimensional array (tensor) given in canonical form, we propose fast algorithm based on cross approximation of Gram matrices of unfoldings.

Keywords:

Multidimensional array canonical decomposition Tucker approximation fast recompression.
