In this repo we implent algorithms for the exact solution to rank-1 L1-norm Tucker2 decompostion of 3-ways tensors as they have been presented in [1].

The exact solution to rank-1 L1-norm TUCKER2 decomposition. PP Markopoulos, DG Chachlakis, EE Papalexakis. IEEE Signal Processing Letters 25 (4), 511-515, 2018.

This letter studies the rank-1 L1-norm-based TUCKER2 (L1-TUCKER2) decomposition of 3-way tensors. First, we prove that the problem is formally NP-hard.

Moreover, for N=3, we propose two algorithms that approximate the solution to general rank Tucker2 decomposition efficiently; one that follows an alternating- ...
