Researchers have introduced a new framework for diffusion models that integrates causal structures, enabling them to perform causal analysis. This causality-encoded diffusion model can approximate observational distributions and facilitate interventional sampling by manipulating specific variables within a directed acyclic graph. The framework also includes a novel resampling-based test for identifying directed edges in causal graphs, with theoretical guarantees on distribution estimation and error control for the edge test. Initial simulations and an application to flow cytometry data suggest the method's effectiveness in recovering interventional distributions and assessing causal relationships. AI
