Abstract :
Post-nonlinear mixtures give a practical nonlinear mixing scenario. Multilayer perceptron is a good choice for adjusting the post-nonlinearity and is taken in both of the two given post-nonlinear source separation algorithms. The difference lies in that the first one switches between fixed distribution models while the second realizes a soft learning on a new flexible yet simple distribution model
