What is ICA blind source separation?

Blind Source Separation (BSS) refers to a problem where both the sources and the mixing methodology are unknown, only mixture signals are available for further separation process. In several situations it is desirable to recover all individual sources from the mixed signal, or at least to segregate a particular source.

What is blind audio source separation?

Blind Audio Source Separation (BASS) consists in recovering one or several source signals from a given mixture signal. Direct applications include real-time speaker separation for simultaneous translation, sampling of musical sounds for electronic music composition.

What is the difference between PCA and ICA?

PCA vs ICA

Specifically, PCA is often used to compress information i.e. dimensionality reduction. While ICA aims to separate information by transforming the input space into a maximally independent basis.

What is ICA method?

In signal processing, independent component analysis (ICA) is a computational method for separating a multivariate signal into additive subcomponents. This is done by assuming that at most one subcomponent is Gaussian and that the subcomponents are statistically independent from each other.
