22 Nov 2009 (Clearly, this was written as part of their campaign to make technical articles accessible.) In normal people words, ICA is a form of blind source separation — a method of unmixing signals after they have been mixed together, without knowing exactly how they were mixed. It's not as bad as Wikipedia makes
11 Apr 2014 Abstract: Independent component analysis (ICA) has become a standard data analysis technique applied to an array of problems in signal processing and machine learning. This tutorial provides an introduction to ICA based on linear algebra formulating an intuition for ICA from first principles. The goal of
Projection Methods and the Fast ICA Algorithm. Background: Data from real-world experiments often naturally arise in the form of collections of values of a (possibly large) number, say p, of variables. Such data are thus most naturally depicted in a p-dimensional scatter diagram. For p>3 this is both difficult to draw and

ICA is a quite powerful technique and is able (in principle) to separate independent sources linearly mixed in several sensors. For instance, when recording electroencephalograms (EEG) on the scalp, ICA can separate out artifacts embedded in the data (since they are usually independent of each other). This page intends
Independent Component Analysis is a powerful tool for eliminating several important types of non-brain artifacts from EEG data. EEGLAB allows the user to reject many such artifacts in an efficient and user-friendly manner. This short tutorial is designed to guide impatient users who want to try using EEGLAB to remove
While this may be desirable in certain situations, sometimes we want to learn a linearly independent basis for the data. In independent component analysis (ICA), this is exactly what we want to do. Further, in ICA, we want to learn not just any linearly independent basis, but an orthonormal basis for the data. (An orthonormal

Then, in Section 7, typical applications of ICA are covered: removing artefacts from brain signal recordings, finding hidden factors in financial time series, and reducing noise in natural images.
