Conformal Counterfactual Inference under Hidden Confounding

no code implementations20 May 2024 Zonghao Chen, Ruocheng Guo, Jean-François Ton, Yang Liu

Personalized decision making requires the knowledge of potential outcomes under different treatments, and confidence intervals about the potential outcomes further enrich this decision-making process and improve its reliability in high-stakes scenarios.

Fair Classifiers that Abstain without Harm

no code implementations9 Oct 2023 Tongxin Yin, Jean-François Ton, Ruocheng Guo, Yuanshun Yao, Mingyan Liu, Yang Liu

To generalize the abstaining decisions to test samples, we then train a surrogate model to learn the abstaining decisions based on the IP solutions in an end-to-end manner.

Inference-time Stochastic Ranking with Risk Control

no code implementations12 Jun 2023 Ruocheng Guo, Jean-François Ton, Yang Liu, Hang Li

Widely used deterministic LTR models can lead to unfair exposure distribution, especially when items with the same relevance receive slightly different ranking scores.

BayesIMP: Uncertainty Quantification for Causal Data Fusion

no code implementations NeurIPS 2021 Siu Lun Chau, Jean-François Ton, Javier González, Yee Whye Teh, Dino Sejdinovic

While causal models are becoming one of the mainstays of machine learning, the problem of uncertainty quantification in causal inference remains challenging.
