Catégorisation automatique de pages web chinoises - documents spécialisés vs grand public sur le tabagisme

Text categorization (or supervised classification) generally addresses the topic or the type of a text. We tackle here a different dimension, the intended audience, contrasting two broad categories: texts intended for the general public, or texts intended for specialists. We test the categorization, according to this contrast, of Chinese Web pages about smoking. In this context, we obtain the f...

Is Naïve Bayes a Good Classifier for Document Classification?

Document classification is a growing interest in the research of text mining. Correctly identifying the documents into particular category is still presenting challenge because of large and vast amount of features in the dataset. In regards to the existing classifying approaches, Naïve Bayes is potentially good at serving as a document classification model due to its simplicity. The aim of this...

A New Method to Improve Automated Classification of Heart Sound Signals: Filter Bank Learning in Convolutional Neural Networks

Introduction: Recent studies have acknowledged the potential of convolutional neural networks (CNNs) in distinguishing healthy and morbid samples by using heart sound analyses. Unfortunately the performance of CNNs is highly dependent on the filtering procedure which is applied to signal in their convolutional layer. The present study aimed to address this problem by a...
