Jeux stochastiques et contrôle de puissance distribué
François Mériaux, Maël Le Treust, Samson Lasaulce +1
Transmitters of a multiple access channel are assumed to freely choose their power control strategy in order to be energy-efficient. We show that in a stochastic game framework, we…
Online algorithms for Nonnegative Matrix Factorization with the Itakura-Saito divergence
Augustin Lefèvre, Francis Bach, Cédric Févotte
Nonnegative matrix factorization (NMF) is now a common tool for audio source separation. When learning NMF on large audio databases, one major drawback is that the complexity in ti…
Testing for homogeneity of variance in the wavelet domain
Olaf Kouamo, Eric Moulines, François Roueff
The danger of confusing long-range dependence with non-stationarity has been pointed out by many authors. Finding an answer to this difficult question is of importance to model tim…
Consistency of functional learning methods based on derivatives
Fabrice Rossi, Nathalie Villa-Vialaneix
In some real world applications, such as spectrometry, functional models achieve better predictive performances if they work on the derivatives of order m of their inputs rather th…
Distributed Stochastic Approximation for Constrained and Unconstrained Optimization
Pascal Bianchi, Jérémie Jakubowicz
In this paper, we analyze the convergence of a distributed Robbins-Monro algorithm for both constrained and unconstrained optimization in multi-agent systems. The algorithm searche…
OMP-type Algorithm with Structured Sparsity Patterns for Multipath Radar Signals
Tabea Rebafka, Céline Lévy-Leduc, Maurice Charbit
A transmitted, unknown radar signal is observed at the receiver through more than one path in additive noise. The aim is to recover the waveform of the intercepted signal and to si…
