SVRMU @ IEEE ICASSP2018

 Stochastic variance reduced multiplicative updates

The software is available at Github.

This code provides a solver of the stochastic MU rule for a large-scale NMF problem, with a variance-reduced (VR) technique of stochastic gradient. This is published in IEEE ICASSP2018.  

OLSTEC @ IEEE ICASSP2016

OnLine Low-rank Subspace tracking by TEnsor CP Decomposition

The software is available at Github.

This package contains an implementation of OLSTEC, an online tensor subspace tracking algorithm based on the Canonical Polyadic decomposition (CP decomposition) (or PARAFAC or CANDECOMP decomposition) exploiting the recursive least squares (RLS), which is published in Neurocomputing and IEEE ICASSP2016. See the detailed explanation of the algorithm here.

HybridPrecodingOpt @ IEEE GlobalSIP2018
