Estimating the Information Potential with the Fast Gauss Transformonverges to the actual entropy value rapidly with increasing order p unlike the Stochastic Information Gradient, the present O(.) approximation to reduce the computational complexity in ITL. We test the performance of these FGT methods on System Identification with encouraging results.

Differential Fast Fixed-Point BSS for Underdetermined Linear Instantaneous Mixturess therefore based on a differential sphering, followed by the optimization of the differential kurtosis that we introduce in this paper. Experimental tests show that this differential method is much more robust to noise than standard FastICA.

Equivariant Algorithms for Estimating the Strong-Uncorrelating Transform in Complex Independent Compoduces the strong uncorrelating transform when the circularity coefficients of the sources are distinct and positive. Simulations show the efficacy of the approach in a source clustering task for wireless communications.

New Permutation Algorithms for Causal Discovery Using ICAber of variables considered is large. Thus we extend the applicability of the method to data sets with tens of variables or more. Experiments confirm the performance of the proposed algorithms, implemented as part of the latest version of our freely available Matlab/Octave LiNGAM package.

Simple LU and QR Based Non-orthogonal Matrix Joint Diagonalizationlem by a sequence of simple one dimensional minimization problems. In addition, a new scale-invariant cost function for non-orthogonal joint diagonalization is employed. These algorithms are step-size free. Numerical simulations demonstrate the efficiency of the methods.

Introduction
