Dans le contexte de la catégorisation de documents, la sélection des descripteurs est une étape de pré-traitement importante qui permet non seulement de réduire la taille de l’index, mais aussi d’améliorer les performances des classifieurs. Parmi les approches utilisées pour construire un sous-ensemble de l’index, on peut distinguer d’une part, les méthodes de réduction de dimensions qui génère...

ACKNOWLEOOMENTS I wish to express my special gratitude to Professor Patrick Suppes, who formulated the problems I worked on, and whose advice, guidance and encouragement at all stages of this work was invaluable. I also want to thank the other members of the reading committee, Professor ~oravcsik and Professor Hintikka, whose criticisms and suggestions were extremely useful, George Huff, who ma...

We define a quantitative semantics for evaluating the strength of arguments in Bipolar Argumentation frameworks (BAFs) by adapting the DiscontinuityFree QuAD (DF-QuAD) algorithm previously used for evaluating the strength of arguments in Quantitative Argumentation Debates (QuAD) frameworks. We study the relationship between the new semantics and some existing semantics for other argumentation f...

The maximization through signal design of the symmetric capacity of CDMA systems with optimal and minimum mean-square error decision feedback (MMSE-DF) decoding is considered. In particular, lower bounds on maximum symmetric capacity (and the signal set that achieves them) are derived for the two decoders. A common sufficient condition is obtained for both decoders under which the signal design...

Résumé. Les Dépendances Fonctionnelles Conditionnelles (DFC) ont été introduites en 2007 pour le nettoyage des données. Elles peuvent être considérées comme une unification de Dépendances Fonctionnelles (DF) classiques et de Règles d’Association (RA) puisqu’elles permettent de spécifier des dépendances mixant des attributs et des couples de la forme attribut/valeur. Dans cet article, nous trait...

In this paper, the principal objective is to validate a new approach for the field-strength estimate in VHF and UHF radio links partially over water. The method is compared with measurements conducted in the cities of Belo Horizonte, MG, and Braslia, DF, Brazil. The approach is based on physical insights applied in the Recommendation ITU-R P.1546-2 mixed path treatment. The results show good ag...

A joint power and time slot partitioning scheme based on the channel status information (CSI) is proposed for networks of multiple relays using decode and forward (DF) protocol. A set of power constraints for the famous water pouring method is presented depending on the time slot partitioning and CSI. Optimizing the timing and the power distributions enhances the network throughput in addition ...

The estimation of direction of arrival (DOA) is the main study of the direction finding and location of radio signal, MUSIC algorithm is the most classic DOA estimation. MUSIC algorithm can estimate independent signals’ DOA effectively, but it is failure to coherent signals. Concerning the issue, the modified MUSIC algorithm works when the correlative signals exist. However, the estimation perf...
