Novel weighting and resampling schemes in Population Monte Carlo

International audience; In this paper we focus on novel population Monte Carlo schemes that present added flexibility and superior performance compared to the standard approach. The new schemes combine different weighting and resampling strategies to achieve more efficient performance at the cost of a reasonable computational complexity increment. Computer simulations compare the different alternatives when applied to the problem of frequency estimation in superimposed sinusoids.; Dans cet article, nous nous concentrons sur de nouveaux schémas de population Monte Carlo présentant une flexibilité et des performance supérieures par rapportàrapport`rapportà l'approche standard. Ces nouveaux sc…
