Summary
A constraint spatial non-negative matrix factorization (CSNMF) technique is proposed for separation of event-related, movement-related and activated regions of the brain from the rest of the fMRI sequence. NMF is a powerful decomposition approach and an emerging technique for analysis of multivariate. The goal of NMF is to decompose a data matrix X into two other matrices, which results in the extraction of some latent features whilst reducing some redundancies in the original data. Inherently, this is an ill-posed problem. Here, a solution to this optimisation problem will be given by incorporating EEG signals into a CSNMF system.
