Bayesian independent component analysis: Variational methods and non-negative decompositions
In this paper we present an empirical Bayesian framework for independent component analysis. The framework provides estimates of the sources, the mixing matrix and the noise parameters, and is flexible with respect to choice of source prior and the number of sources and sensors. Inside the engine of the method are two mean field techniques – the variational Bayes and the expectation consistent ...
متن کاملVariational Bayesian Independent Component Analysis
Blind separation of signals through the info-max algorithm may be viewed as maximum likelihood learning in a latent variable model. In this paper we present an alternative approach to maximum likelihood learning in these models, namely Bayesian inference. It has already been shown how Bayesian inference can be applied to determine latent dimensionality in principal component analysis models (Bi...
متن کاملVariational Bayesian Learning for Wavelet Independent Component Analysis
In an exploratory approach to data analysis, it is often useful to consider the observations as generated from a set of latent generators or “sources” via a generally unknown mapping. For the noisy overcomplete case, where we have more sources than observations, the problem becomes extremely ill-posed. Solutions to such inverse problems can, in many cases, be achieved by incorporating prior kno...
متن کاملPost-nonlinear Independent Component Analysis by Variational Bayesian Learning
Post-nonlinear (PNL) independent component analysis (ICA) is a generalisation of ICA where the observations are assumed to have been generated from independent sources by linear mixing followed by component-wise scalar nonlinearities. Most previous PNL ICA algorithms require the post-nonlinearities to be invertible functions. In this paper, we present a variational Bayesian approach to PNL ICA ...
متن کاملbayesian analysis of non-normal and non-independent mixed model usingskew-normal/independent distributions
the main assumptions in liner mixed model are normality and independency of random effect component. unfortunately, these two assumptions might be unrealistic in some situations. therefore, in this paper, we will discuss about the analysis of bayesian analysis of non-normal and non-independent mixed model using skew-normal/independent distributions, and finally, thi...
