Independent Component Analysis : A Tutorial Introduction (A Bradford Book)

Rating:
Summary: An Excellent Introduction
Review: Independent Component Analysis (ICA) is one of the emerging technologies that ever more powerful computers are becoming more available. Basically it is a set of mathematical techniques that are used to pull a little bit of information out of a large mass of data.

Much of ICA's applicability has to do with signal processing. The amount of data that a radar antenna receives, for instance, is huge with respect to the amount of data that actually reflects back from the target.

Similar problems occur in many types of signal processing, i.e. brain imaging, speech processing, telecommunications and other signals. Other types of large data volume, small signal interest occurs in stock market analysis, weather prediction, various biomedical applications, etc.

This overview first establishes the strategy implicit in ICA and then goes on to give the mathematical procedures and processes that are involved along with some computer programs that implement the mathematics. This is an excellent introduction to the concepts.
