Independent component analysis (MLR-ICAN)

A Parameter-Free Cauchy-Schwartz Information Measure for Independent Component Analysis

Lei Sun

Independent component analysis (ICA) by an information measure has seen wide applications in engineering. Different from traditional probability density function based information measures, a probability survival distribution based Cauchy-Schwartz information measure for multiple variables is proposed in this paper. Empirical estimation of survival distribution is parameter-free which is inherited by the estimation of the new information measure.

Unsupervised Keyword Spotting using Bounded Generalized Gaussian Mixture Model with ICA

Muhammad Azam

In this paper, bounded generalized Gaussian mixture model (BGGMM) using independent component analysis (ICA) is proposed and applied to an existing unsupervised keyword spotting setting for the generation of posteriorgrams. The ICA mixture model is trained without any transcription information to generate the posteriorgrams which further labels the speech frames of the keyword example(s) and test data.
