Cohérence et qualité des informations de contexte en environnement pervasif

Context management in pervasive environments becomes a key element for the development of new applications. However, the intrinsic properties of pervasive systems impact the consistency of context information. The composition of distributed observations collected from different sources may cause the introduction of potential inconsistencies. Besides, context information is highly dynamic and ev...

Modélisation de HMM en contexte avec des arbres de décision pour la reconnaissance de mots manuscrits

This paper presents an HMM-based recognizer for the off-line recognition of handwritten words. Word models are the concatenation of context-dependent character models: the trigraphs. Due to the large number of possible context-dependent models to compute, a clustering is applied on each state position, based on decision trees. Our system is shown to perform better than a baseline context indepe...
