Set-valued classification--overview via a unified framework

E Chzhen, C Denis, M Hebiri, T Lorieul - arXiv preprint arXiv:2102.12318, 2021 - arxiv.org
Multi-class classification problem is among the most popular and well-studied statistical
frameworks. Modern multi-class datasets can be extremely ambiguous and single-output …

Leveraging labeled and unlabeled data for consistent fair binary classification

E Chzhen, C Denis, M Hebiri… - Advances in Neural …, 2019 - proceedings.neurips.cc
We study the problem of fair binary classification using the notion of Equal Opportunity. It
requires the true positive rate to distribute equally across the sensitive groups. Within this …

Selective classification via one-sided prediction

A Gangrade, A Kag… - … Conference on Artificial …, 2021 - proceedings.mlr.press
We propose a novel method for selective classification (SC), a problem which allows a
classifier to abstain from predicting some instances, thus trading off accuracy against …

Fair regression via plug-in estimator and recalibration with statistical guarantees

E Chzhen, C Denis, M Hebiri… - Advances in Neural …, 2020 - proceedings.neurips.cc
We study the problem of learning an optimal regression function subject to a fairness
constraint. It requires that, conditionally on the sensitive feature, the distribution of the …

Uncertainty in predictions of deep learning models for fine-grained classification

T Lorieul - 2020 - theses.hal.science
Deep neural networks have shown dramatic improvements in a lot of supervised
classification tasks. Such models are usually trained with the objective to ultimately minimize …

Nearest neighbor based conformal prediction

L Gyôrfi, H Walk - Annales de l'ISUP, 2019 - hal.science
In this paper we introduce a nearest neighbor based estimate of the prédiction interval with
prescribed conditional coverage probability and with small length. In the spécial case, when …

Classification under ambiguity: when is average-k better than top-k?

T Lorieul, A Joly, D Shasha - arXiv preprint arXiv:2112.08851, 2021 - arxiv.org
When many labels are possible, choosing a single one can lead to low precision. A common
alternative, referred to as top-$ K $ classification, is to choose some number $ K $(commonly …

Regression under demographic parity constraints via unlabeled post-processing

E Chzhen, M Hebiri, G Taturyan - arXiv preprint arXiv:2407.15453, 2024 - arxiv.org
We address the problem of performing regression while ensuring demographic parity, even
without access to sensitive attributes during inference. We present a general-purpose post …

Nonparametric active learning for cost-sensitive classification

BN Njike, X Siebert - arXiv preprint arXiv:2310.00511, 2023 - arxiv.org
Cost-sensitive learning is a common type of machine learning problem where different
errors of prediction incur different costs. In this paper, we design a generic nonparametric …

Learning fair models and representations

L Oneto - Intelligenza Artificiale, 2020 - content.iospress.com
Abstract Machine learning based systems and products are reaching society at large in
many aspects of everyday life, including financial lending, online advertising, pretrial and …
