Differentially Private Multi-Site Treatment Effect Estimation

no code implementations10 Oct 2023 Tatsuki Koga, Kamalika Chaudhuri, David Page

In this work, we take a fresh look at federated learning with a focus on causal inference; specifically, we look at estimating the average treatment effect (ATE), an important task in causal inference for healthcare applications, and provide a federated analytics approach to enable ATE estimation across multiple sites along with differential privacy (DP) guarantees at each site.
