ICA by Minimization of Mutual Information An important approach for independent component analysis (ICA) estimation, inspired by information theory, is minimization of mutual information. The motivation of this approach is that it may not be very realistic in many cases to assume that the data follows the ICA model. Therefore, we would like to develop an approach that does not assume anything about the data. What we want to have is a general-purpose measure of the dependence of the components of a random vector. Using such a measure, we could define ICA as a linear decomposition that minimizes that dependence measure....
