Intégration de la reconnaissance des entités nommées au processus de reconnaissance de la parole

We are interested in the recognition of named entities for the speech modality. Some difficulties may arise for this task due to speech processing. In this work, we propose to study the tight pairing between the speech recognition task and the named entity recognition task. For that purpose, we take away the basic functionnalities of a speech recognition system to turn it into a named entity re...

Vers la reconnaissance de mini-messages manuscrits

Handwriting is an alternative method for entering texts which composed Short Message Services. However, a whole new language features the texts which are produced. They include for instance abbreviations and other consonantal writing which sprung up for time saving and fashion. We have collected and processed a significant number of such handwritten SMS, and used various strategies to tackle th...

Sélection de la structure d'un perceptron multicouches pour la réduction dun modèle de simulation d'une scierie

Résumé— La simulation est souvent utilisée pour évaluer la pertinence d’un Programme Directeur de Production (PDP) ou pour en évaluer l’impact sur des scénarii d’ordonnancement détaillés de la fabrication. Dans ce cadre, nous nous proposons de réduire la complexité d’un modèle de simulation en exploitant un perceptron multicouches. Une phase primordiale lors de la modélisation d’un système à l’...

Représentations d ’ images pour la reconnaissance de formes

One of the main requirements in many signal processing applications is to have a “meaningful representation” in which signal’s characteristics are readily apparent. For example, for recognition, the representation should highlight salient features; for denoising, it should efficiently separate signal and noise; and for compression, it should capture a large part of signal using only a few coeff...
