Modeling and Estimation of Dependent Subspaces with Non-radially Symmetric and Skewed Densitiesan random variables linked by a common variance. We also introduce the modeling of skew in source densities and subspaces using a generalization of the Normal Variance-Mean mixture model. We give closed form expressions for subspace likelihoods and parameter updates in the EM algorithm.

On the Relationships Between Power Iteration, Inverse Iteration and FastICAg numerical linear algebra tools. A recent result shows that the FastICA algorithm, a popular state-of-the-art method for linear Independent Component Analysis (ICA), shares a nice interpretation as a Newton type method with the Rayleigh Quotient Iteration (RQI), the latter method wellknown to the n

A Sufficient Condition for the Unique Solution of Non-Negative Tensor Factorizationential for NNTF to have a unique solution. In this paper we give a sufficient condition for NNTF to have a unique global optimal solution. For a third-order tensor . we define a matrix by some rearrangement of . and it is shown that the rank of the matrix is less than or equal to the rank of .. It i

Colored Subspace Analysisata sets becomes an increasingly important challenge. Classical dimension reduction techniques such as principal component analysis often do not take the large statistics of the data set into account, and thereby fail if the signal space is for example of low power but meaningful in terms of some ot

Is the General Form of Renyi’s Entropy a Contrast for Source Separation?’s entropy and its computational advantages in specific cases. These criteria were suggested based on “convincing” experiments. However, there is no theoretical proof that globally maximizing those functions would lead to separate the sources; actually, this was implicitly conjectured. In this paper

A Variational Bayesian Algorithm for BSS Problem with Hidden Gauss-Markov Models for the Sources The data are . images and the sources are . images which are assumed piecewise homogeneous. To insure these properties, we propose a piecewise Gauss-Markov model for the sources with a hidden classification variable which is modeled by a Potts-Markov field. A few simulation results are given to ill

A New Source Extraction Algorithm for Cyclostationary Sourcessignals and hidden periodicities such as those induced by modulation for communications and by rotating machines for vibrations. In some cases, the fundamental frequency of these repetitive phenomena can be known. The algorithm that we propose aims at extracting one cyclostationary source, whose cyc
