Rôle de la matrice d'information et pondération des composantes dans les noyaux de Fisher pour PLSI

Jean-Cédric Chappelier, Emmanuel Eckard

ABSTRACT. An information-geometric approach for document similarities in the framework of “Probabilistic Latent Semantic Indexing” was ﬁrst proposed by T. Hofmann (2000) and later extended (“revisited”) by Nyffenegger et al. (2006). This paper presents an ...

An Ad Hoc Information Retrieval Perspective on PLSI through language model identification

Jean-Cédric Chappelier, Emmanuel Eckard

Ten years ago, PLSI opened the road to probabilistic latent semantic representations of documents. It led to a number of applications in different ﬁelds, including ad hoc Information Retrieval. However, inherent limitations hinder its use on documents not ...

PLSI: The True Fisher Kernel and beyond IID Processes, Information Matrix and Model Identification in PLSI

Jean-Cédric Chappelier, Emmanuel Eckard

The Probabilistic Latent Semantic indexing model, introduced by T. Hofmann (1999), has engendered applications ill numerous fields, notably document classification and information retrieval. In this context, the Fisher kernel was found to be an appropriate ...

Motion constraint

Ronan Boulic, Daniel Raunhardt

In this paper, we propose a hybrid postural control approach taking advantage of data-driven and goal-oriented methods while overcoming their limitations. In particular, we take advantage of the latent space characterizing a given motion database. We intro ...

Observable Subspaces for 3D Human Motion Recovery

Pascal Fua, Mathieu Salzmann, Andrea Fossati

The articulated body models used to represent human motion typically have many degrees of freedom, usually expressed as joint angles that are highly correlated. The true range of motion can therefore be represented by latent variables that span a low-dimen ...

How to play the “Names Game”: Patent retrieval comparing different heuristics

Stéphane Lhuillery, Julio Diego Salvador Raffo

Patent statistics represent a critical tool for scholars, statisticians and policy makers interested in innovation and intellectual property rights. Many analyses are based on heterogeneous methods delineating the inventors’ or firms’ patent portfolios wit ...

Approximating geometric crossover in semantic space

Pawel Lichocki

We propose a crossover operator that works with genetic programming trees and is approximately geometric crossover in the semantic space. By defining semantic as program's evaluation profile with respect to a set of fitness cases and constraining to a spec ...
