A Stochastic Proximal Method for Nonsmooth Regularized Finite Sum Optimization

1 code implementation14 Jun 2022 Dounia Lakhmiri, Dominique Orban, Andrea Lodi

We consider the problem of training a deep neural network with nonsmooth regularization to retrieve a sparse and efficient sub-structure.

Use of static surrogates in hyperparameter optimization

no code implementations14 Mar 2021 Dounia Lakhmiri, Sébastien Le Digabel

Optimizing the hyperparameters and architecture of a neural network is a long yet necessary phase in the development of any new application.

Tuning a variational autoencoder for data accountability problem in the Mars Science Laboratory ground data system

no code implementations6 Jun 2020 Dounia Lakhmiri, Ryan Alimo, Sebastien Le Digabel

The Mars Curiosity rover is frequently sending back engineering and science data that goes through a pipeline of systems before reaching its final destination at the mission operations center making it prone to volume loss and data corruption.

HyperNOMAD: Hyperparameter optimization of deep neural networks using mesh adaptive direct search

1 code implementation3 Jul 2019 Dounia Lakhmiri, Sébastien Le Digabel, Christophe Tribes

The performance of deep neural networks is highly sensitive to the choice of the hyperparameters that define the structure of the network and the learning process.
