Mémoire sur l’évolution de la condition féminine de 1945 à nos jours : Etude comparative d’après les ouvrages de: - Le Deuxième sexe de Simone de Beauvoir - Fausse route d’Elisabeth Badinter

Ce mémoire n’a pas la prétention d’aborder la totalité des combats menés par ces deux personnalités, Simone de Beauvoir et Elisabeth Badinter, pour la libération des femmes. Cependant, il permet de mettre en évidence, voire en parallèles les actions essentielles de deux femmes de générations différentes. Avec une même sensibilité et une pugnacité sans faille malgré les difficultés et  critiques rencontrées, elles ont permis à l’ensemble des hommes et surtout des femmes de prendre conscience des inégalités à combattre pour un meilleur « vivre ensemble ».

Multiclass Adaboost Based on an Ensemble of Binary Adaboosts

This paper presents a multi-class AdaBoost based on incorporating an ensemble of binary AdaBoosts which is organized as Binary Decision Tree (BDT). It is proved that binary AdaBoost is extremely successful in producing accurate classification but it does not perform very well for multi-class problems. To avoid this performance degradation, the multi-class problem is divided into a number of binary problems and binary AdaBoost classifiers are invoked to solve these classification problems. This approach is tested with a dataset consisting of 6500 binary images of traffic signs. Haar-like features of these images are computed and the multi-class AdaBoost classifier is invoked to classify them. A classification rate of 96.7% and 95.7% is achieved for the traffic sign boarders and pictograms, respectively. The proposed approach is also evaluated using a number of standard datasets such as Iris, Wine, Yeast, etc. The performance of the proposed BDT classifier is quite high as compared with the state of the art and it converges very fast to a solution which indicates it as a reliable classifier.
