Singular Value Decomposition (SVD), and Independent Component Analysis (ICA). Both of these techniques utilize a representation of the data in a statistical domain rather than a time or frequency domain. That is, the data is projected onto a new set of axes that fulll some statistical criterion, which imply independence, rather than a set of axes that represent discrete frequencies such as In this paper the authors gives an introduction for independent component analysis which is different from principle component analysis. In which optimize for statistical independence of given data.

Independent component analysis is a useful extension of the principal component analysis (PC A). It has been developed some years ago in context with blind source separation ap­ component analysis (ICA) to transform the multivariate data to a set of univariate time series that are mutually independent, thereby allowing for the much broader class of univariate models to provide seasonal forecasts for each transformed series.

Independent component analysis (ICA) is a Statistical and computational technique in which the goal is to find a linear projection of the data that the source signals or components are statistically independent or as independent as possible. It is probably fair to say that in the last 10 years, ICA has become a standard tool in machine learning and signal processing [11].

Independent component analysis (ICA) is becoming an increasingly important tool for analyzing large data sets. In essence, ICA separates an observed set of signal mixtures into a set of statistically independent component signals, or source signals. In so doing, this powerful method can extract the relatively small amount of useful information typically found in large data sets.
