Client-specific A-stack model for adult face verification across aging

The problem of time validity of biometricmodels has received only a marginal attention from researchers. In this paper, we propose to manage the aging influence on the adult face verification system by an A-stack age modeling technique, which uses the age ...

Mode choice with attitudinal latent class: a Swiss case-study

Michel Bierlaire, Aurélie Glerum, Bilge Atasoy

Attitudinal attributes play an important role in behavior of individuals in various contexts. In this study we focus on the travel behavior and our main objective is to come up with segments of individuals that have different mode choice preferences with t ...

Model misspecification in peaks over threshold analysis

Anthony Christopher Davison, Mária Süveges

Classical peaks over threshold analysis is widely used for statistical modeling of sample extremes, and can be supplemented by a model for the sizes of clusters of exceedances. Under mild conditions a compound Poisson process model allows the estimation of ...

On the Validity of the Fixed Point Equation and Decoupling Assumption for Analyzing the 802.11 MAC Protocol

Jean-Yves Le Boudec

Abstract—Performance evaluation of the 802.11 MAC protocol is classically based on the decoupling assumption, which hypothesizes that the backoff processes at different nodes are independent. A necessary condition for the validity of this approach is the e ...

Global And Local Feature Based Multi-Classifier A-Stack Model For Aging Face Identification

Andrzej Drygajlo, Weifeng Li

The problem of time validity of biometric models has received only a marginal attention from researchers. Actual and up-to-date at the time of their creation, extracted features and models relevant to a person's face may eventually become outdated, leading ...

Validity and Reliability of a French Version of the Metacognitions Questionnaire in a Nonclinical Population

Mathieu d'Acremont

We investigated the psychometric properties of a French translation of the Metacognitions Questionnaire (MCQ). 265 participants from the French-speaking population of Belgium completed the MCQ. Construct validity was assessed by means of a factor analysis, ...

On the naturality of the exterior differential

Marc Troyanov

We give sufficient conditions for the naturallity of the exterior differential under Sobolev mappings. In other words we study the validity of the equation

d\, f^* \alpha = f^*\; d\alpha

for a smooth form

\alpha

and a Sobolev map

f

Pelvic Motion Implementation on the WalkTrainer

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Patrick Métrailler, Jacques Fournier, Yves Allemand

Pelvic motion is of great importance when walking, and have thus to be taken into account while developing rehabilitation robotics. This paper describes the implementation of a pelvic motion amplitude prediction model on a pelvic orthosis and tests on vali ...

Discrete mixture Models

Michel Bierlaire

Allowing for variations in behaviour across respondents is one of the most fundamental principles in discrete choice modelling, given that the assumption of a purely homogeneous population cannot in general be seen to be valid. Two approaches have classica ...
