08/11/2012 @ 13h30 – 17h30 – 13h30 Optimization of High Dimensional Functions: Application to a Pulse Shaping Problem, Mattias Gybels, LIF. 14h Nonlinear functional data analysis with reproducing kernels, Hachem Kadri, LIF. 14h30 Confused Multiclass Relevance Vector Machine, Ugo Louche, LIF. 15h Automatic Drum Transcription with informed NM, Antoine Bonnefoy, LIF. 15h30 Coffee break. 16h Proximal methods for multiple removal in […]
18/10/2012 @ 14h00 – 15h00 – A multicomponent proximal algorithm for Empirical Mode Decomposition. By Nelly Pustelnik, ENS Lyon The Empirical Mode Decomposition (EMD) is known to be a powerful tool adapted to the decomposition of a signal into a collection of intrinsic mode functions (IMF). A key procedure in the extraction of the IMFs is the sifting process whose main […]
27/09/2012 @ 14h00 – 15h00 – Learning from structured fMRI patterns using graph kernels. (by Sylvain Takerkart, LIF). Classification of medical images in multi-subjects settings is a difficult challenge due to the variability that exists between individuals. Here we introduce a new graph-based framework specifically designed to deal with inter-subject functional variability present in functional MRI data. A graphical representation is […]
20/09/2012 @ 14h00 – 15h00 – Phase Reconstruction Problem: Recent Advances and Applications for Audio Signals (by Anaik Olivero, LIF/LATP). « Tout est dans le titre. »
13/09/2012 @ 14h00 – 15h00 – Matching pursuit with stochastic selection (by Thomas Peel, LIF). We propose a Stochastic Selection strategy that ac- celerates the atom selection step of Matching Pursuit. This strategy consists of randomly selecting a subset of atoms and a subset of rows in the full dictionary at each step of the Matching Pursuit to obtain a sub-optimal […]
03/02/2012 @ 14h00 – 16h00 – I review what is known about the preservation and/or loss of the Gibbs property for various models in which continuous spins are subjected to diffusive evolutions, with or without interaction. I shortly mention some results on discretising continuous spins. This reflects mostly joint work with Kuelske,Opoku and Ruszel. I will end with discussing some preliminary […]
03/02/2012 @ 10h00 – 12h00 – Gibbs measures are the mathematical formalization of Boltzmann-Gibbs distributions and describe equilibrium states of extended systems in statistical mechanics. If one starts a system in equilibrium and subjects it to a dynamics, modelling e.g. heating or cooling, a natural question is whether some “effective” interaction describes the transient non-equilibrium states that the systems goes through. […]
02/12/2011 @ 14h00 – 16h00 – Jacob van den Berg and Alberto Gandolfi Introduction, review and new developments.
31/03/2010 @ 11h00 – 12h00 – We propose a novel distance based method for reconstruction of phylogenetic trees. Our method is based on a conceptual clustering method that extends the decision tree learning approach. Our method starts from a single cluster and repeatedly splits it into subclusters until all sequences form a different cluster. We assume that a split can be […]
17/03/2010 @ 9h00 – 10h00 – il y aura un exposé de l’intervenante le Mardi 16 mars (horaire à préciser, CMI) http://www.cmap.polytechnique.fr/~veber/ Amandine Véber
