Improvement Of Audiovisual Quality Estimation Using A Nonlinear Autoregressive Exogenous Neural Network And Bitstream Parameters

no code implementations28 Feb 2024 Koffi Kossi, Stephane Coulombe, Christian Desrosiers, Ghyslain Gagnon

In this paper, we developed a parametric model for estimating the perceived audiovisual quality in videoconference services.

Designing a Pseudo-Random Bit Generator with a Novel 5D-Hyperchaotic System

no code implementations19 May 2021 Ngoc T. Nguyen, Toan Q. Bui, Ghyslain Gagnon, Pascal Giard, Georges Kaddoum

Moreover, a data scrambling circuit is implemented to eliminate the bias effect and increase the randomness of the bitstream generated from the chaotic signals.

Energy Disaggregation using Variational Autoencoders

1 code implementation22 Mar 2021 Antoine Langevin, Marc-André Carbonneau, Mohamed Cheriet, Ghyslain Gagnon

In this paper we address these issues and propose an energy disaggregation approach based on the variational autoencoders framework.

Bag-Level Aggregation for Multiple Instance Active Learning in Instance Classification Problems

no code implementations6 Oct 2017 Marc-André Carbonneau, Eric Granger, Ghyslain Gagnon

In such cases, active learning (AL) can reduce labeling costs for training a classifier by querying the expert to provide the labels of most informative instances.

Multiple Instance Learning: A Survey of Problem Characteristics and Applications

1 code implementation11 Dec 2016 Marc-André Carbonneau, Veronika Cheplygina, Eric Granger, Ghyslain Gagnon

Multiple instance learning (MIL) is a form of weakly supervised learning where training instances are arranged in sets, called bags, and a label is provided for the entire bag.

Feature Learning from Spectrograms for Assessment of Personality Traits

no code implementations4 Oct 2016 Marc-André Carbonneau, Eric Granger, Yazid Attabi, Ghyslain Gagnon

The number of features, and difficulties linked to the feature extraction process are greatly reduced as only one type of descriptors is used, for which the 6 parameters can be tuned automatically.
