Lissage rapide dans des modèles non linéaires et non gaussiens

We consider here the problem of statistical filtering and smoothing in nonlinear non-Gaussian systems. The novelty consists in approximating the nonlinear system by a recent switching system, in which exact fast optimal filtering and smoothing are workable. Our methods are applied to an asymetric stochastic volatility model and some experiments show their efficiency.

Extraction et interprétation d'information géographique dans des données non structurées

This paper outlines the “Pyrénées Itinéraires Virtuels” project. The aim of this project is to add value to a legacy localised corpus. Unified models are proposed to define spatial entities in a formal way. These models allow to build a specific information retrieval system based on the semantic contents of various kinds of documents. Moreover, a reflection on computable interpretation of these...

Recherche d'information précise dans des sources d'information structurées et non structurées : défis, approches et hybridation

This paper provides a synthesis of text-based Question Answering (QA) approaches, with emphasis on models exploiting structured representations of texts, and recent QA approaches for knowledge bases. Our goal is to show the common issues, and to identify what can be a common approach, using both the relations from textual documents and the triplets from knowledge bases. We present a few works u...
