Group-wise oracle-efficient algorithms for online multi-group learning

no code implementations7 Jun 2024 Samuel Deng, Daniel Hsu, Jingwen Liu

We study the problem of online multi-group learning, a learning model in which an online learner must simultaneously achieve small prediction regret on a large collection of (possibly overlapping) subsequences corresponding to a family of groups.

Multi-group Learning for Hierarchical Groups

no code implementations1 Feb 2024 Samuel Deng, Daniel Hsu

The multi-group learning model formalizes the learning scenario in which a single predictor must generalize well on multiple, possibly overlapping subgroups of interest.

Group conditional validity via multi-group learning

no code implementations7 Mar 2023 Samuel Deng, Navid Ardeshir, Daniel Hsu

We consider the problem of distribution-free conformal prediction and the criterion of group conditional validity.

Learning Tensor Representations for Meta-Learning

no code implementations18 Jan 2022 Samuel Deng, Yilin Guo, Daniel Hsu, Debmalya Mandal

Prior works on learning linear representations for meta-learning assume that there is a common shared representation across different tasks, and do not consider the additional task-specific observable side information.

Ensuring Fairness Beyond the Training Data

2 code implementations NeurIPS 2020 Debmalya Mandal, Samuel Deng, Suman Jana, Jeannette M. Wing, Daniel Hsu

In this work, we develop classifiers that are fair not only with respect to the training distribution, but also for a class of distributions that are weighted perturbations of the training samples.

Methodological Blind Spots in Machine Learning Fairness: Lessons from the Philosophy of Science and Computer Science

no code implementations31 Oct 2019 Samuel Deng, Achille Varzi

In the ML fairness literature, there have been few investigations through the viewpoint of philosophy, a lens that encourages the critical evaluation of basic assumptions.
