The linear mixture model is assumed in most of the papers devoted to blind separation. A more realistic model for mixture should be non-linear. In this paper, a two-layer perceptron is used as a de-mixing system to separate sources in non-linear mixture. The learning algorithms for the de-mixing system are derived by two approaches: maximum entropy and minimum mutual information. The algorithms derived from the two approaches have a common structure. The new learning equations for the hidden… CONTINUE READING
