Abstract:
The properties of training data set such as size, distribution and the number of attributes significantly contribute to the generalization error of a learning machine. A not well-distributed data set is prone to lead to a partial overfitting model. Two approaches proposed in this dissertation for the binary classification enhance useful data information by mining negative data. First, an error driven compensating hypothesis approach is based on Support Vector Machines (SVMs) with (1+k)-iteration learning, where the base learning hypothesis is iteratively compensated k times. This approach prod

Internet Service Providers (ISPs) and network operators benefit from knowing what type of traffic that propagates over their network in order to correctly treat different applications. Today Deep Packet Inspection (DPI) and port based classification are two of the more commonly used methods in order to classify Internet traffic. However, both of these techniques fail when the traffic is encrypted. This study explores a third method, classifying Internet traffic b

Abstract:
Ce projet de recherche cible l’étude et l’amélioration de la précision de la classification d’images de phytoplancton et la diminution du temps de traitement moyen requis par image. Deux solutions de classification sont proposées pour atteindre ces objectifs. La première solution vise à effectuer la classification d’images en passant par les phases de prétraitement, de discrimination et de classification, et la deuxième solution utilise uniquement les phases de prétraitement et de classification. En résumé, la phase de prétraitement manipule une image en vue de caractériser l’élément princi

Abstract:
There is a significant need to identify approaches for classifying chemical sensor array data with high success rates that would enhance sensor detection capabilities. The present study attempts to fill this need by investigating six machine learning methods to classify a dataset collected using a chemical sensor array: K-Nearest Neighbor (KNN), Support Vector Machine (SVM), Classification and Regression Trees (CART), Random Forest (RF), Naïve Bayes Classifier (NB), and Principal Component Regression (PCR). A total of 10 predictors that are associated with the response from 10 sensor channels

Abstract:
Text classification is used in information extraction and retrieval from a given text, and text classification has been considered as an important step to manage a vast number of records given in digital form that is far-reaching and expanding. This thesis addresses patent document classification problem into fifteen different categories or classes, where some classes overlap with other classes for practical reasons. For the development of the classification model using machine learning techniques, useful features have been extracted from the given documents. The features are used to classify

Abstract:
La définition d'une métrique entre des séries temporelles est un élément important pour de nombreuses tâches en analyse ou en fouille de données, tel que le clustering, la classification ou la prédiction. Les séries temporelles présentent naturellement différentes caractéristiques, que nous appelons modalités, sur lesquelles elles peuvent être comparées, comme leurs valeurs, leurs formes ou leurs contenus fréquentielles. Ces caractéristiques peuvent être exprimées avec des délais variables et à différentes granularités ou localisations temporelles - exprimées globalement ou localement. Combine

Les capteurs RSO (Radar à Synthèse d'Ouverture) fournissent des observations des surfaces terrestres de manière continue depuis 1991 avec la mise en orbite du satellite ERS-1. Les données acquises jusqu'à peu, principalement basées sur l'exploitation de l'intensité du signal acquis selon une configuration de polarisation particulière, ont été l'objet de nombreuses études, notamment sur le suivi de la déforestation. Depuis 2007, de nouveaux capteurs RSO polarimétriques (PALSAR, RADARSAT-2, TerraSAR-X...) permettent la caractérisation polarimétrique des surfaces observées. Ces données nécessiten

With the great growth of open forums online where anyone can givetheir opinion on everything, the Internet has become a place wherepeople are trying to mislead others. By assuming that there is acorrelation between a deceptive text's purpose and the way to writethe text, our goal with this thesis was to develop a model fordetecting these fake texts by taking advantage of this correlation.Our approach was to use classification together with threedifferent feature types, term frequency-inverse document frequency,word2vec and probabilistic context-free grammar.
