Diffusion Model in Causal Inference with Unmeasured Confounders

Published in 2023 IEEE Symposium Series On Computational Intelligence, 2023

We study how to extend the use of the diffusion model to answer the causal question from the observational data under the existence of unmeasured confounders.
