Semiparametric Inference for Counterfactual Regression under Intervention-Driven Shift

Read the original on arXiv Machine Learning →

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.

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.

FCx: An algorithm for finding Feasible Counterfactual Explanations

FCx is a new algorithm that generates counterfactual explanations while explicitly enforcing feasibility constraints. It uses a modified Variational Autoencoder with a multi‑factor loss to produce realistic, low‑cost counterfactuals that satisfy both hard constraints supplied by users and soft constraints inferred via causal inference. Experiments on four public datasets demonstrate that FCx matches state‑of‑the‑art performance across multiple metrics while guaranteeing feasibility.
