Description: 

A fundamental problem in neural network research, and many other disciplines, isfinding a suitable representation of multivariate data. For  computational simplicity, the representation is often sought as a linear transformation of the original data. Different from well-known linear transformation methods (such as PCA, factor analysis, and projection pursuit), the Independent Component Analysis (ICA) is a method aiming to represent the data via linearly combining hidden components which are “non-Gaussian” and “statistically independent”. Such a representation seems to capture the essential structure of the data in many applications, useful for feature extraction and signal separation. This short course introduces the basic theory, numerical algorithms, and recent research works on ICA, with applications to neuroscience, genetics and finance.
