A Recursive Decomposition Framework for Causal Structure Learning in the Presence of Latent Variables

ICML 2026oral

Constraint-based causal discovery is widely used for learning causal structures, but heavy reliance on conditional independence (CI) testing makes it computationally expensive in high-dimensional settings. To mitigate this limitation, many divide-and-conquer frameworks have been proposed, but most a…

Data-Driven Selection of Instrumental Variables for Additive Nonlinear, Constant Effects Models

ICML 2025poster

We consider the problem of selecting instrumental variables from observational data, a fundamental challenge in causal inference. Existing methods mostly focus on additive linear, constant effects models, limiting their applicability in complex real-world scenarios. In this paper, we tackle a more…

Local Learning for Covariate Selection in Nonparametric Causal Effect Estimation with Latent Variables

NeurIPS 2025poster

Estimating causal effects from nonexperimental data is a fundamental problem in many fields of science. A key component of this task is selecting an appropriate set of covariates for confounding adjustment to avoid bias. Most existing methods for covariate selection often assume the absence of laten…
