Utilisation de la quantification vectorielle sur un système de reconnaissance de parole continue a approche globale
(Université de Sherbrooke, 1984)
L'objet de ce mémoire de maîtrise est d'évaluer l'intérêt que peut avoir en reconnaissance de parole l'utilisation de la technique de quantification vectorielle. En effet, le développement de la quantification vectorielle ...

Analyse et reconnaissance des consonnes nasales, liquides et fricatives indépendamment du locuteur pour intégration dans un système de reconnaissance automatique de parole alliant approches cognitive et statistique
(Université de Sherbrooke, 1988)
Le présent document s'intéresse à l'analyse et à la reconnaissance des consonnes nasales, liquides et fricatives indépendamment du locuteur pour les chiffres et lettres de l'alphabet en anglais. Nous proposons deux analyses ...
Synergistic activity between primary visual neurons
(2014)
Abstract : Cortical microcircuitry plays a pivotal role in encoding sensory information reaching the
cortex. However, the fundamental knowledge concerning the mechanisms that govern
feature-encoding by these sub-networks ...
Comparison of the statistical and information theory measures: application to automatic musical genre classification
(2007)
Abstract:
Recently considerable research has been conducted to retrieve pertinent parameters and adequate models for automatic music genre classification using different databases. Many of previous works are derived from ...
Modulation of functional connectivity following visual adaptation: homeostasis in V1
(2015)
Abstract: Sensory neurons exhibit remarkable adaptability in acquiring new optimal selectivity to unfamiliar features when a new stimulus becomes prevalent in the environment. In conventionally prepared adult anesthetized ...
High noise correlation between the functionally connected neurons in emergent V1 microcircuits
(2016)
Abstract : Neural correlations (noise correlations and cross-correlograms) are widely studied to infer functional connectivity between neurons. High noise correlations (Rsc) between neurons have been reported to increase ...
Objets sonores : une représentation bio-inspirée, hiérarchique, parcimonieuse à très grandes dimensions utilisable en reconnaissance
(2013)
L’accent est placé dans cet article sur la structure hiérarchique, l’aspect parcimonieux de la représentation
de l’information sonore, la très grande dimension des caractéristiques ainsi que sur l’indépendance des ...
Performance of three acoustical methods for localizing whales in the Saguenay - St. Lawrence Marine Park
(2008)
Abstract : Three algorithms are explored to localize fin whale calls recorded from a large-aperture hydrophone array deployed in the Saguenay—St. Lawrence Marine Park. The methods have to cope with varying sound speed in ...
Brain at work : time, sparseness and superposition principles
(2012)
Abstract : Many studies explored mechanisms through which the brain encodes sensory inputs allowing a
coherent behavior. The brain could identify stimuli via a hierarchical stream of activity leading to a cardinal
neuron ...
