A Counterfactual Semantics for Hybrid Dynamical Systems

NeurIPS 2025poster

Models of hybrid dynamical systems are widely used to answer questions about the causes and effects of dynamic events in time. Unfortunately, existing causal reasoning formalisms lack support for queries involving the dynamically triggered, discontinuous interventions that characterize hybrid dynami…

Automated Efficient Estimation using Monte Carlo Efficient Influence Functions

NeurIPS 2024spotlight

Many practical problems involve estimating low dimensional statistical quantities with high-dimensional models and datasets. Several approaches address these estimation tasks based on the theory of influence functions, such as debiased/double ML or targeted minimum loss estimation. We introduce \tex…

Causal Inference using Gaussian Processes with Structured Latent Confounders

ICML 2020poster

Latent confounders—unobserved variables that influence both treatment and outcome—can bias estimates of causal effects. In some cases, these confounders are shared across observations, e.g. all students taking a course are influenced by the course’s difficulty in addition to any educational interven…
