Efficient Constrained Tensor Factorization by Alternating Optimization with Primal-Dual Splitting
ICASSP 2018accepted
Tensor factorization with hard and/or soft constraints has played an important role in signal processing and data analysis. However, existing algorithms for constrained tensor factorization have two drawbacks: (i) they require matrix-inversion; and (ii) they cannot (or at least is very difficult to)…
