Qin Shu · Communications technology · 2009
This paper starts from the definition of ICA,explains the applications and how to solve the correlative questions. Some independent component analysis algorithms and their features are discussed,and the priors used in independent component analysis are summarized in this paper,including the mathematical definition of ICA,the assumptions made about ICA problems,and the mathematical theory and methods commonly used in ICA,etc. Finally,this paper gives equivalences and differences of the methods mentioned,and discuss where is the best place belonging to the methods.
