[EN] Abstract
Surrogate methods are very useful in nonlinearities detection application and
supervised detection or classification where there aren’t available sufficient data. In
both cases it’s needed optimize ...
[EN] Conventional partial correlation coefficients (PCC) were extended to the non-Gaussian case, in particular to independent component analysis (ICA) models of the observed multivariate samples. Thus, the usual methods ...

Currently, novel forms of shared media experiences between remote users are gaining momentum.
Relevant examples are Social TV, synchronous e-learning and multiplayer online games. This work
presents the design, development ...
[EN] Recent works in signal processing on graphs have been driven to estimate the precision matrix and to use it as the graph Laplacian matrix. The normalized elements of the precision matrix are the partial correlation ...
