Data-Driven Estimation of Heterogeneous Treatment Effects

no code implementations16 Jan 2023 Christopher Tran, Keith Burghardt, Kristina Lerman, Elena Zheleva

In this work, we provide a survey of state-of-the-art data-driven methods for heterogeneous treatment effect estimation using machine learning, broadly categorizing them as methods that focus on counterfactual prediction and methods that directly estimate the causal effect.

counterfactual

Improving Data-driven Heterogeneous Treatment Effect Estimation Under Structure Uncertainty

1 code implementation25 Jun 2022 Christopher Tran, Elena Zheleva

To address this problem, we develop a feature selection method that considers each feature's value for HTE estimation and learns the relevant parts of the causal structure from data.

1 code implementation31 Jan 2019 Christopher Tran, Elena Zheleva

The causal effect of a treatment can vary from person to person based on their individual characteristics and predispositions.
