Discriminant Multi-Label Manifold Embedding for Facial Action Unit Detection

Jean-Philippe Thiran, Anil Yuce, Hua Gao

This article describes a system for participation in the Facial Expression Recognition and Analysis (FERA2015) sub-challenge for spontaneous action unit occurrence detection. The problem of AU detection is a multi-label classification problem by its nature ...

Semi-supervised multiview embedding for hyperspectral data classification

Devis Tuia, Giona Matasci

In this paper, a method for semi-supervised multiview feature extraction based on the multiset regularized kernel canonical correlation analysis (kCCA) is proposed for the classification of hyperspectral images. The covariance matrix of this type of data i ...

Anti-spoofing: Evaluation Methodologies

Sébastien Marcel, André Anjos, Ivana Chingovska

Following the definition of the task of the anti-spoofing systems to discriminate between real accesses and spoofing attacks, anti-spoofing can be regarded as a binary classification problem. The spoofing databases and the evaluation methodologies for anti ...

Comparing multiple testing procedures and error rates under weighted classification

Dimitri Nestor Alice Van De Ville, Stephan Morgenthaler, Djalel Eddine Meskaldji

When many hypotheses are tested simultaneously, the control of the number of false rejections is often the principal consideration. In practice, this is insatisfacory since we also have to keep in mind the power of detecting true effects. At the moment, th ...

Classification of selectively constrained DNA elements using feature vectors and rule-based classifiers

Philipp Bucher, Slavica Dimitrieva Janeva

Scarce work has been done in the analysis of the composition of conserved non-coding elements (CNEs) that are identified by comparisons of two or more genomes and are found to exist in all metazoan genomes. Here we present the analysis of CNEs with a metho ...

A Wireless Body Sensor Network For Activity Monitoring With Low Transmission Overhead

David Atienza Alonso, Andreas Peter Burg, Ruben Braojos Lopez, Jeremy Hugues-Felix Constantin, Ivan Beretta

Activity recognition has been a research field of high interest over the last years, and it finds application in the medical domain, as well as personal healthcare monitoring during daily home- and sports-activities. With the aim of producing minimum disco ...

Intrusion Detection in MANET Using Classification Algorithms: The Effects of Cost and Model Selection

Christos Dimitrakakis, Aikaterini Mitrokotsa

Intrusion detection is frequently used as a second line of defense in Mobile Ad-hoc Networks (MANETs). In this paper we examine how to properly use classification methods in intrusion detection for MANETs. In order to do so we evaluate five supervised clas ...

Improved Local Binary Pattern Based Action Unit Detection Using Morphological and Bilateral Filters

Jean-Philippe Thiran, Matteo Sorci, Anil Yuce

Automatic facial action unit (AU) detection in videos is the key ingredient to all systems that utilize a subject face for either interaction or analysis purposes. With the ever growing range of possible applications, achieving a high accuracy in the simpl ...

Physical activity recognition via minimal in-shoes force sensor configuration

Kamiar Aminian, Arash Arami, Fabien Massé, Christopher Moufawad El Achkar

We propose a new minimal wearable system and a classifier for physical activity recognition. The configuration is solely based on two force sensors placed anteriorly and posteriorly under the feet. To find the optimal sensor configuration, we estimated the ...
