Bounded Component Analysis (BCA) is a recently introduced framework which can be considered as an extension of Independent Component Analysis (ICA) for bounded magnitude signals. In BCA, the boundedness of signals is exploited to replace independence assumption with a weaker ‘‘domain separability’’ assumption. As a result BCA algorithms can be used to separate dependent as well as independent signals from their mixtures. In this talk, I'll introduce a geometric approach for developing instantaneous and convolutive BCA algorithms. Furthermore, the potential benefits of the corresponding BCA algorithms are illustrated through different application examples.

This is a joint work with Huseyin A. Inan.
