Abstract

Constrained joint analysis of data from multiplesources has received widespread attention for that it allowsus to explore potential connections and extract meaningful hidden components. In this paper, we formulate a flexible jointsource separation model termed as group nonnegative matrix factorization with sparse regularization (GNMF-SR), which aimsto jointly analyze the partially coupled multi-set data. In the GNMF-SR model, common and individual patterns of particular underlying factors can be extracted simultaneously with imposing nonnegative constraint and sparse penalty. Alternating optimization and alternating direction method of multipliers (ADMM) are combined to solve the GNMF-SR model. Using the experimentof simulated fMRI-like data, we demonstrate the ADMM-basedGNMF-SR algorithm can achieve the better performance.
