This paper proposes a new strategy to separate astrophysical sources that are mutually correlated. This strategy is based on second-order statistics and exploits prior information about the possible structure of the mixing matrix. Unlike ICA blind separation approaches, where the sources are assumed mutually independent and no prior knowledge is assumed about the mixing matrix, our strategy allows the independence assumption to be relaxed and performs the separation of even significantly…

Extracting Astrophysical Sources from Channel-Dependent Convolutional Mixtures by Correlated Component Analysis in the Frequency Domain

A second-order statistical technique (FD-CCA) for semi-blind source separation from multiple-sensor data is presented. It works in the Fourier domain and allows us to both learn the unknown mixing

Fully Bayesian Blind Source Separation of Astrophysical Images Modelled by Mixture of Gaussians

In this work, we address the problem of source separation in the presence of prior information. We develop a fully Bayesian source separation technique which assumes a generic model for the sources,

Dependent Gaussian mixture models for source separation

A factor analysis model for source separation of multi-spectral image data where prior information about the sources and their dependencies is quantified as a multivariate Gaussian mixture model with an unknown number of factors is looked at.

Multidimensional ICA and its performance analysis applied to CMB observations

The authors' simulations show a good match between the closed-form analytical expression for the error and its empirical counterpart, which can serve as a reliable predictor of the separation error without resorting to exhaustive Monte-Carlo trials.

This work presents a novel technique, namely particle filtering, for the non-blind (Bayesian) solution of the source separation problem, in case of non-stationary sources and noise, by exploiting available a-priori information.

Sparse component separation for accurate cosmic microwave background estimation

The cosmic microwave background (CMB) is of premier importance for cosmologists in studying the birth of our universe. Unfortunately, most CMB experiments, such as COBE, WMAP, or Planck do not

Second-Order Multidimensional ICA: Performance Analysis

A more general and more flexible model: the sources can be partitioned into groups exhibiting dependence within a given group but independence between two different groups, which is tantamount to considering multidimensional components as opposed to the standard ICA case which is restricted to one-dimensional components.



Neural networks and the separation of cosmic microwave background and astrophysical signals in sky maps

We implement an independent component analysis (ICA) algorithm to separate signals of different origin in sky maps at several frequencies. Owing to its self-organizing capability, it works without

A new source separation technique exploiting the time coherence of the source signals is introduced, which relies only on stationary second-order statistics that are based on a joint diagonalization of a set of covariance matrices.
