Abduction-Deduction Entanglement: Domain Generalization via Representation Transplants

arXiv:2605.25156v1 Announce Type: new Abstract: Prediction models trained under the source distribution do not generalize well to a different target distribution. A valid inference about an unseen data distribution must be anchored by the invariance of certain causal mechanisms that generate the source and target data, however, these structural invariances are non-identifiable from the source data alone. Under mild causal assumptions about the data, we show that the optimal prediction in the target is in fact partially identifiable by the source distribution. The result rests on a simple obser

Why this matters
Why now

This research addresses a fundamental challenge in AI generalization, which becomes increasingly critical as AI models are deployed in diverse, real-world environments beyond their training data.

Why it’s important

Improving AI's ability to generalize to unseen distributions is crucial for more robust and reliable autonomous systems and agents, expanding their applicability and trustworthiness.

What changes

The explicit identification of partially identifiable optimal prediction in target distributions based on source data marks a theoretical advancement in domain generalization.
