Enhancing Counterfactual Estimation: A Focus on Temporal Treatments

IJCAI 2025

In the medical field, treatment sequences significantly influence future outcomes through complex temporal interactions. Therefore, highlighting the role of temporal treatments within the model is crucial for accurate counterfactual estimation, which is often overlooked in current methods. To addres

Generation-Augmented and Embedding Fusion in Document-Level Event Argument Extraction

COLING 2025main

Document-level event argument extraction is a crucial task that aims to extract arguments from the entire document, beyond sentence-level analysis. Prior classification-based models still fail to explicitly capture significant relationships and heavily relies on large-scale datasets. In this study,…

Variational Counterfactual Intervention Planning to Achieve Target Outcomes

ICML 2025poster

A key challenge in personalized healthcare is identifying optimal intervention sequences to guide temporal systems toward target outcomes, a novel problem we formalize as counterfactual target achievement. In addressing this problem, directly adopting counterfactual estimation methods face compoundi…

A Dual-module Framework for Counterfactual Estimation over Time

ICML 2024poster

Efficiently and effectively estimating counterfactuals over time is crucial for optimizing treatment strategies. We present the Adversarial Counterfactual Temporal Inference Network (ACTIN), a novel framework with dual modules to enhance counterfactual estimation. The balancing module employs a dist…

Generalization Bounds for Estimating Causal Effects of Continuous Treatments

NeurIPS 2022accept

We focus on estimating causal effects of continuous treatments (e.g., dosage in medicine), also known as dose-response function. Existing methods in causal inference for continuous treatments using neural networks are effective and to some extent reduce selection bias, which is introduced by non-ran…
