Jensen-Shannon divergence, Fisher information, and Wootters' hypothesis

open access: yes, 2004
We discuss different statistical distances in probability space, with emphasis on the Jensen-Shannon divergence, vis-a-vis {\it metrics} in Hilbert space and their relationship with Fisher's information measure. This study provides further reconfirmation of Wootters' hypothesis concerning the possibility that statistical fluctuations in the outcomes of

A new method to measure the divergence in evidential sensor data fusion

open access: yesInternational Journal of Distributed Sensor Networks, 2019
Evidence theory is widely used in real applications such as target recognition because of its efficiency in evidential sensor data fusing. However, counter-intuitive results may be obtained in the situation when evidence highly conflicts with each other.

Directed Network Comparison Using Motifs

open access: yesEntropy
Analyzing and characterizing the differences between networks is a fundamental and challenging problem in network science. Most previous network comparison methods that rely on topological properties have been restricted to measuring differences between ...

Entropy Analysis of Soccer Dynamics

open access: yesEntropy, 2019
This paper adopts the information and fractional calculus tools for studying the dynamics of a national soccer league. A soccer league season is treated as a complex system (CS) with a state observable at discrete time instants, that is, at the time of ...

Using the Jensen-Shannon, Density Power, and Itakura-Saito Divergences to Implement an Evolutionary-Based Global Localization Filter for Mobile Robots

open access: yesIEEE Access, 2017
One of the most demanding skills for a mobile robot is to be intelligent enough to know its own location. The global localization problem consists of obtaining the robot's pose (position and orientation) in a known map if the initial location is unknown.

Studying Lexical Dynamics and Language Change via Generalized Entropies: The Problem of Sample Size

open access: yesEntropy, 2019
Recently, it was demonstrated that generalized entropies of order α offer novel and important opportunities to quantify the similarity of symbol sequences where α is a free parameter.

Correspondances compatibles avec les fichiers inverses pour la recherche d'information.

open access: yes, 2014
National audienceCet article fait un retour sur l'un des éléments majeurs d'un système de recherche d'information : la correspondance basée sur des fichiers inverses car le passage d'une formule théorique à une implantation compatible avec des ...
