Constraint Setting in Constrained ICA
Guangyun Wang, Qiu Langbo, Gang Wang, Zhengzhi Wang · 2006
Constraint setting is a crucial part in constrained independent component analysis (CICA) and directly affects the result of CICA's application in blind source separation (BSS), etc.. In this paper, constraints are sorted into three types. Based on numerical optimistic algorithms, the corresponding formula and the setting method for each type are presented, and the adjustable parameter in the formula of constraints is emphasized. Experimental results show that constraints in CICA can be set reasonably and effectively by the proposed methods
