Abstract
Renyi's entropy can be used as a cost function for blind source separation (BSS). Previous works have emphasized the advantage of setting Renyi's exponent to a value different from one in the context of BSS. In this paper, we focus on zero-order Renyi's entropy minimization for the blind extraction of bounded sources (BEBS). We point out the advantage of choosing the extended zero-order Renyi's entropy as a cost function in the context of BEBS, when the sources have non-convex supports.
