Interfaces adaptatives Adaptation dynamique à l'utilisateur courant

We present a survey of recent research studies of the implementation of adaptive user models in human-computer interaction. A classification of research directions on adaptive user interfaces is first proposed; it takes account of the user characteristics that are modelled, the distribution of initiative and control of the system evolution between user and system, and the role of dynamic adapta...

Nouveau modèle pour la datation automatique de photographies à partir de caractéristiques visuelles

We present in this paper, a method for dating photographs by using their visual content. We were inspired by recent works in computer vision. We improved the classification method used in their work by overcoming an intrinsic limit of their approach. Indeed, they consider dating photographs as a multi-class classification problem, for which a class represents a set of years, but ignoring the re...
