[PDF][PDF] DEAP: Evolutionary algorithms made easy

…, MAG Gardner, M Parizeau, C Gagné - The Journal of Machine …, 2012 - jmlr.org
DEAP is a novel evolutionary computation framework for rapid prototyping and testing of ideas.
Its design departs from most other existing frameworks in that it seeks to make algorithms …

Probabilistic sensing model for sensor placement optimization based on line-of-sight coverage

V Akbarzadeh, C Gagne, M Parizeau… - IEEE transactions on …, 2012 - ieeexplore.ieee.org
This paper proposes a probabilistic sensor model for the optimization of sensor placement.
Traditional schemes rely on simple sensor behaviour and environmental factors. The …

Robustness to adversarial examples through an ensemble of specialists

M Abbasi, C Gagné - arXiv preprint arXiv:1702.06856, 2017 - arxiv.org
We are proposing to use an ensemble of diverse specialists, where speciality is defined
according to the confusion matrix. Indeed, we observed that for adversarial instances originating …

Bayesian hyperparameter optimization for ensemble learning

JC Lévesque, C Gagné, R Sabourin - arXiv preprint arXiv:1605.06394, 2016 - arxiv.org
In this paper, we bridge the gap between hyperparameter optimization and ensemble learning
by performing Bayesian optimization of an ensemble with regards to its hyperparameters. …

[HTML][HTML] A machine learning approach for online automated optimization of super-resolution optical microscopy

…, LÉ Robitaille, A Bilodeau, C Gagné… - Nature …, 2018 - nature.com
Traditional approaches for finding well-performing parameterizations of complex imaging
systems, such as super-resolution microscopes rely on an extensive exploration phase over …

Multi-objective evolutionary optimization for generating ensembles of classifiers in the ROC space

JC Lévesque, A Durand, C Gagné… - Proceedings of the 14th …, 2012 - dl.acm.org
In this paper, we propose a novel approach for the multi-objective optimization of classifier
ensembles in the ROC space. We first evolve a pool of simple classifiers with NSGA-II using …

Learning to predict indoor illumination from a single image

…, E Yumer, X Shen, E Gambaretto, C Gagné… - arXiv preprint arXiv …, 2017 - arxiv.org
We propose an automatic method to infer high dynamic range illumination from a single,
limited field-of-view, low dynamic range photograph of an indoor scene. In contrast to previous …

The surprising creativity of digital evolution: A collection of anecdotes from the evolutionary computation and artificial life research communities

J Lehman, J Clune, D Misevic, C Adami, L Altenberg… - Artificial life, 2020 - direct.mit.edu
Evolution provides a creative fount of complex and subtle adaptations that often surprise the
scientists who discover them. However, the creativity of evolution is not limited to the natural …

Deap: A python framework for evolutionary algorithms

…, FA Fortin, MA Gardner, M Parizeau, C Gagné - Proceedings of the 14th …, 2012 - dl.acm.org
DEAP (Distributed Evolutionary Algorithms in Python) is a novel volutionary computation
framework for rapid prototyping and testing of ideas. Its design departs from most other existing …

Demand-side management using deep learning for smart charging of electric vehicles

KL López, C Gagné, MA Gardner - IEEE Transactions on Smart …, 2018 - ieeexplore.ieee.org
The use of electric vehicles (EVs) load management is relevant to support electricity demand
softening, making the grid more economic, efficient, and reliable. However, the absence of …
