Analysis of Bootstrap and Subsampling in High-dimensional Regularized Regression

no code implementations21 Feb 2024 Lucas Clarté, Adrien Vandenbroucque, Guillaume Dalle, Bruno Loureiro, Florent Krzakala, Lenka Zdeborová

We investigate popular resampling methods for estimating the uncertainty of statistical models, such as subsampling, bootstrap and the jackknife, and their performance in high-dimensional supervised regression tasks.

Expectation consistency for calibration of neural networks

2 code implementations5 Mar 2023 Lucas Clarté, Bruno Loureiro, Florent Krzakala, Lenka Zdeborová

Despite their incredible performance, it is well reported that deep neural networks tend to be overoptimistic about their prediction confidence.

Uncertainty Quantification

Theoretical characterization of uncertainty in high-dimensional linear classification

1 code implementation7 Feb 2022 Lucas Clarté, Bruno Loureiro, Florent Krzakala, Lenka Zdeborová

In this manuscript, we characterise uncertainty for learning from limited number of samples of high-dimensional Gaussian input data and labels generated by the probit model.
