Finite Sample Confidence Regions for Linear Regression Parameters Using Arbitrary Predictors

no code implementations27 Jan 2024 Charles Guille-Escuret, Eugene Ndiaye

We explore a novel methodology for constructing confidence regions for parameters of linear models, using predictions from any arbitrary predictor.

Expecting The Unexpected: Towards Broad Out-Of-Distribution Detection

1 code implementation22 Aug 2023 Charles Guille-Escuret, Pierre-André Noël, Ioannis Mitliagkas, David Vazquez, Joao Monteiro

Our findings reveal that while these methods excel in detecting unknown classes, their performance is inconsistent when encountering other types of distribution shifts.

Towards Out-of-Distribution Adversarial Robustness

1 code implementation6 Oct 2022 Adam Ibrahim, Charles Guille-Escuret, Ioannis Mitliagkas, Irina Rish, David Krueger, Pouya Bashivan

Compared to existing methods, we obtain similar or superior worst-case adversarial robustness on attacks seen during training.

A Study of Condition Numbers for First-Order Optimization

no code implementations10 Dec 2020 Charles Guille-Escuret, Baptiste Goujaud, Manuela Girotti, Ioannis Mitliagkas

Since smoothness and strong convexity are not continuous, we propose a comprehensive study of existing alternative metrics which we prove to be continuous.

InsectUp: Crowdsourcing Insect Observations to Assess Demographic Shifts and Improve Classification

no code implementations30 May 2019 Léonard Boussioux, Tomás Giro-Larraz, Charles Guille-Escuret, Mehdi Cherti, Balázs Kégl

Insects play such a crucial role in ecosystems that a shift in demography of just a few species can have devastating consequences at environmental, social and economic levels.
