In this paper, we present experimental results on a non­ linear independent component analysis approach based on Bayesian ensemble learning. The theory of the method is discussed in a companion paper. Simulations with artiøcial and natural data demonstrate the feasi­ bility and good performance of the proposed approach. We also discuss the relationships of the method to other existing methods.
