Fast adaptive PARAFAC decomposition algorithm with linear complexity

Viet-Dung Nguyen, Karim Abed-Meraim, Nguyen Linh-Trung

ICASSP 2016accepted

We present a fast adaptive PARAFAC decomposition algorithm with low computational complexity. The proposed algorithm generalizes the Orthonormal Projection Approximation Subspace Tracking (OPAST) approach for tracking a class of third-order tensors which have one dimension growing with time. It has…

Parallelizable PARAFAC decomposition of 3-way tensors

Viet-Dung Nguyen, Karim Abed-Meraim, Linh-Trung Nguyen

ICASSP 2015accepted

This paper introduces a new PARAFAC algorithm for a class of third-order tensors. Particularly, the proposed algorithm is based on subspace estimation and solving a non-symmetrical joint diagonalization problem. To deal with large scale problem, a procedure for overcoming scale and permutation ambig…
