Guaranteed Tensor Decomposition: A Moment Approach

ICML 2015poster

We develop a theoretical and computational framework to perform guaranteed tensor decomposition, which also has the potential to accomplish other tensor tasks such as tensor completion and denoising. We formulate tensor decomposition as a problem of measure estimation from moments. By constructing a…

Sparse and Low-Rank Tensor Decomposition

Parikshit Shah, Nikhil Rao, Gongguo Tang

NeurIPS 2015poster

Motivated by the problem of robust factorization of a low-rank tensor, we study the question of sparse and low-rank tensor decomposition. We present an efficient computational algorithm that modifies Leurgans' algoirthm for tensor factorization. Our method relies on a reduction of the problem to spa…
