Non-convex Regularizations for Feature Selection in Ranking With Sparse SVM
Léa Laporte, Rémi Flamary, Stephane Canu +2
Feature selection in learning to rank has recently emerged as a crucial issue. Whereas several preprocessing approaches have been proposed, only a few works have been focused on in…
Geometric side of a local relative trace formula
Patrick Delorme, Pascale Harinck, Sofiane Souaifi
Following a scheme suggested by B. Feigon, we investigate a local relative trace formula in the situation of a reductive -adic group relative to a symmetric subgroup $H= \u…
Detecting single-trial EEG evoked potential using a wavelet domain linear mixed model: application to error potentials classification
J Spinnato, M-C Roubaud, B Burle +1
Objective. The main goal of this work is to develop a model for multi-sensor signals such as MEG or EEG signals, that accounts for the inter-trial variability, suitable for corresp…
Rigidity of Determinantal Point Processes with the Airy, the Bessel and the Gamma Kernel
Alexander I. Bufetov
A point process is said to be rigid if for any bounded domain in the phase space, the number of particles in the domain is almost surely determined by the restriction of the config…
On the distribution of the trace in the unitary symplectic group and the distribution of Frobenius
Gilles Lachaud
The purpose of this article is to study the distribution of the trace on the unitary symplectic group. We recall its relevance to equidistribution results for the eigenvalues of th…
Partial analyticity and nodal sets for nonlinear elliptic systems
Herbert Koch, Nikolai Nadirashvili
We study partial analyticity of solutions to elliptic systems and analyticity of level sets of solutions to nonlinear elliptic systems. We consider several applications, including…
