New causal inference methods leverage domain knowledge and novel graph structures

Researchers are developing new methods for causal inference, moving beyond traditional bespoke estimators. One approach, Causal Foundation Models (CFMs), aims to unify causal discovery and inference. A recent advancement allows CFMs to incorporate domain knowledge, such as partial or full causal graphs, by conditioning the model's attention mechanism and using a graph-convolutional encoder. This integration enables CFMs to match the performance of specialized models. Separately, a new framework called the "Napkin" graph has been introduced for causal inference, which can identify average treatment effects through a nonstandard ratio of g-formulas. This framework handles unmeasured confounding and incorporates features of M-bias, instrumental variables, and back-door/front-door settings, offering semiparametric inference theory and demonstrating efficiency gains with accompanying R package implementation.
