Final Comments,user, both in tuning them and in assessing the quality of the results. Simply put, these methods are still very far from a “black box” use, in which one would just grab a separation routine, supply the data, and immediately get useful results.

Introduction,osite page, especially if the paper is thin. In all these cases we obtain signals that are contaminated by other signals, and we would like to get rid of the contamination to recover the original signals.

Nonlinear Separation,e components of . are equal to the components of ., up to some indeterminacies to be clarified later. These indeterminacies will include, at least, permutation and scaling, as in the linear case. As we can see, we are considering only the simplest nonlinear setting, in which there is no noise and the mixing is both instantaneous and invariant.

When we have little knowledge about the sources and about the mixture process, we speak of blind source separation. Linear blind source separation is a relatively well studied s

For example, when trying to obtain an electrocardiogram of the fetus, in a pregnant woman, the fetus’ signals will be contaminated by the much stronger signals from the mother’s heart. When recording speech in a noisy environment, the signals recorded through the microphone(s) w

Nonlinear Separation,called sources and are mutually statistically independent. We observe a mixture vector X, which is related to . by.. being a vector-valued invertible function, which is, in general, nonlinear. Unless stated otherwise, the size of . is assumed to be equal to the size of . i.e., we consider a so-calle
