A non linear analysis for clean and noisy speech
(1991)
Abstract: The research in speech analysis is recognized to be an important aspect in the area of speech processing, with applications in speech coding, speech recognition, etc. Depending on the application, the speech ...
Speaker identification by computer and human evaluated on the SPIDRE corpus
(2000)
Abstract : Closed set speaker identification experiments were performed on a SPIDRE subset of the switchboard corpus with matched and mismatched telephone handset conditions. The impact of mismatched and matched conditions ...
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 ...
Sensorial substitution system with encoding of visual objects into sounds
(2011)
Abstract : Visual and auditory prostheses involve surgeries that are complex, expensive, and invasive. They are limited to a small number of electrodes and can only be used when the impairment is peripheral. The Vibe and ...
Network-selectivity and stimulus-discrimination in the primary visual cortex : cell-assembly dynamics
(2015)
Abstract : Visual neurons coordinate their responses in relation to the stimulus; however, the complex
interplay between a stimulus and the functional dynamics of an assembly still eludes
neuroscientists. To this aim, ...
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 ...
Source separation with one ear : proposition for an anthropomorphic approach
(2005)
Abstract : We present an example of an anthropomorphic approach, in which auditory-based cues are combined with temporal correlation to implement a source separation system. The auditory features are based on spectral ...
Adaptation-induced plasticity and spike-waveforms in cat visual cortex
(2012)
Abstract : Orientation-selective neurons shift their preferred orientation after being adapted to a nonpreferred orientation. These shifts of the peaks of tuning curves may be in the attractive or
repulsive direction in ...
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 ...
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 ...
