A Survey on Federated Causal Discovery and Inference

arXiv:2606.23741v1 Announce Type: cross Abstract: Causal reasoning, which encompasses the discovery of causal structures and the inference of causal effects, is fundamental to data-driven decision making. In practice, data for reliable causal analysis are often distributed across institutions and cannot be centralized due to privacy regulations or communication constraints. Federated learning (FL) addresses this by enabling collaborative analysis without raw data sharing, giving rise to the rapidly growing field of federated causal discovery (FCD) and inference (FCI). However, the interdiscipl

Why this matters
Why now

The increasing focus on data privacy and distributed computing, coupled with the growing maturity of both federated learning and causal AI, is driving this convergence into a nascent field.

Why it’s important

Federated Causal Discovery and Inference addresses a critical challenge in AI: enabling robust causal analysis and data-driven decision-making with distributed, sensitive data, bypassing the need for centralized data pooling.

What changes

The ability to perform sophisticated causal reasoning across siloed datasets without compromising privacy or violating regulations will accelerate AI adoption in highly regulated sectors and improve collaborative intelligence.

Winners
  • · Healthcare sector
  • · Financial services
  • · Academia (collaborative research)
  • · Organizations with sensitive, distributed data
Losers
  • · Traditional centralized data analytics platforms
  • · Organizations unwilling to adopt federated approaches
Second-order effects
Direct

Increased ability to derive causal insights from geographically or organizationally dispersed datasets without compromising privacy.

Second

Accelerated development and deployment of AI applications in highly regulated industries by enabling critical analyses that were previously impossible.

Third

The emergence of new business models focused on secure, privacy-preserving data collaboration and causal discovery as a service.
