Independent Component Analysis

A dimensionality reduction and separation method that aims to decompose mixed signals into statistically independent components.

Independent Component Analysis is especially useful for separating mixed signals and identifying hidden independent sources. Examples include EEG signals, audio mixtures, and some financial time-series settings. Unlike PCA, it does not focus only on variance, but on statistical independence. This makes it a powerful alternative for signal separation and latent structure discovery.
