Chapter 14: A Comparative Study of ICA Based Approaches for Separation of Components in Functional MRI Sequences

Abstract

This paper prepares a review of ICA based approaches that are used for separation of components in functional MRI sequences. In previous works, the FastICA and the Infomax algorithms are investigated in more details; therefore, in this paper we focus on methods such as "radical ICA", "SDD ICA", "Erica" and "Evd" for separation purposes. This comparative study provides reliable framework for brain researchers to choose appropriate ICA based method for their special investigation purposes.
