- Abstract: Many modern applications collect data that comes in federated spirit, with
data kept locally and undisclosed. Till date, most insight into the causal
inference requires data to be stored in a central repository. We present a
novel framework for causal inference with federated data sources. We assess and
integrate local causal effects from different private data sources without
centralizing them. Then, the treatment effects on subjects from observational
data using a non-parametric reformulation of the classical potential outcomes
framework is estimated. We model the potential outcomes as a random function
distributed by Gaussian processes, whose defining parameters can be efficiently
learned from multiple data sources, respecting privacy constraints. We
demonstrate the promise and efficiency of the proposed approach through a set
of simulated and real-world benchmark examples.

Decentralized data sources are prevalent in real-world applications, posing a formidable challenge for causal inference.
