Understanding Why Label Smoothing Degrades Selective Classification and How to Fix It

no code implementations19 Mar 2024 Guoxuan Xia, Olivier Laurent, Gianni Franchi, Christos-Savvas Bouganis

We first demonstrate empirically across a range of tasks and architectures that LS leads to a consistent degradation in SC.

Make Me a BNN: A Simple Strategy for Estimating Bayesian Uncertainty from Pre-trained Models

no code implementations23 Dec 2023 Gianni Franchi, Olivier Laurent, Maxence Leguéry, Andrei Bursuc, Andrea Pilzer, Angela Yao

Deep Neural Networks (DNNs) are powerful tools for various computer vision tasks, yet they often struggle with reliable uncertainty quantification - a critical requirement for real-world applications.

A Symmetry-Aware Exploration of Bayesian Neural Network Posteriors

1 code implementation12 Oct 2023 Olivier Laurent, Emanuel Aldea, Gianni Franchi

The distribution of the weights of modern deep neural networks (DNNs) - crucial for uncertainty quantification and robustness - is an eminently complex object due to its extremely high dimensionality.

Learning to Generate Training Datasets for Robust Semantic Segmentation

no code implementations1 Aug 2023 Marwane Hariat, Olivier Laurent, Rémi Kazmierczak, Shihao Zhang, Andrei Bursuc, Angela Yao, Gianni Franchi

We propose a novel approach to improve the robustness of semantic segmentation techniques by leveraging the synergy between label-to-image generators and image-to-label segmentation models.

Packed-Ensembles for Efficient Uncertainty Estimation

1 code implementation17 Oct 2022 Olivier Laurent, Adrien Lafage, Enzo Tartaglione, Geoffrey Daniel, Jean-Marc Martinez, Andrei Bursuc, Gianni Franchi

Deep Ensembles (DE) are a prominent approach for achieving excellent performance on key metrics such as accuracy, calibration, uncertainty estimation, and out-of-distribution detection.
