In this paper, we report an experimental comparison between two widely used combination methods, i.e. sum and product rules, in order to determine the relationship between their performance and classifier diversity. We focus on the behaviour of the considered combination rules for ensembles of classifiers with different performance and level of correlation.(More)
The use of artificial outputs generated by a classifier simulator has recently emerged as a new trend to provide an underlying evaluation of classifier combination methods. In this paper, we propose a new method for the artificial generation of classifier outputs based on additional parameters which provide sufficient diversity to simulate, for a problem of(More)

Objectives. To estimate the prevalence of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) in a population aged over sixty years with type 2 diabetes and to study the impact of anxiety and depression on glycemic balance and disease outcome. Results. The prevalence of anxiety and depression in the 62 subjects included in the(More)
PURPOSE The aim of this study was to compare the impact of the practice of football and judo on lung function and aerobic performance of prepubertal boys. METHODS A total of ninety six prepubertal boys were studied. They assessed a measure of body composition using the skin folds method. They performed lung plethysmography at rest, followed by an(More)
BACKGROUND Exercise induced bronchospasm (EIB) commonly occurs during exercise. The comparative effects of different sports on airway responsiveness among prepubertal boys remain to be determined. OBJECTIVES To assess differences in post exercise spirometry between footballers, judokas and a control group in prepubertal boys. PATIENTS AND METHODS A(More)
