Safe Bayesian Optimization with Counterfactual Policies

arXiv:2607. 05620v1 Announce Type: cross Abstract: In many decision-making settings, new interventions are acceptable only if they do not reduce outcomes below some established threshold.

Semiparametric Inference for Counterfactual Regression under Intervention-Driven Shift

The paper introduces a semiparametric framework for counterfactual regression along a specified incremental‑intervention path. It estimates a finite‑dimensional constrained projection of counterfactual risk using cross‑fitted influence‑function representations, and establishes consistency, local stability, and first‑order expansions for smooth and finite‑dimensional programs. The results provide asymptotically valid inference, including simultaneous confidence bands, and are demonstrated through simulations and an SMS reminder application.

Interaction-Limited Safe Continuous-Time RL for Dynamical Medical Treatment

arXiv:2606. 01051v1 Announce Type: new Abstract: Dynamic medical treatment requires deciding treatment intensity and intervention timing, while patient states evolve continuously and adverse events may occur between clinical interactions.

Automatic, Debiased, and Invariant Counterfactual Generation under General Interventions

arXiv:2606. 07399v1 Announce Type: cross Abstract: Generative models for counterfactual outcomes have great potential to support decision-making under complex interventions, but existing approaches are limited by unstable estimation, poor generalization across environments, and bias from nuisance model misspecification.

Calibrating Decision Robustness via Inverse Conformal Risk Control

arXiv:2510. 07750v3 Announce Type: replace-cross Abstract: Robust optimization safeguards decisions against uncertainty by optimizing against worst-case scenarios, yet their effectiveness hinges on a prespecified robustness level that is often chosen ad hoc, leading to either insufficient protection or overly conservative and costly solutions.
