Causal representations should be invariant across environments

Representations that capture true causal structure remain stable under distribution shift, unlike purely statistical features that exploit spurious correlations.

“Causal models can be seen as the correct abstraction level for generalizing across domains.”

Reasoning

Because: The ICM principle states causal generative mechanisms are autonomous modules — changing one does not affect others. Representations aligned with these mechanisms inherit their invariance.

Boundaries: Assumes the causal graph is stable across environments. Breaks under structural causal changes. Also assumes we can identify the correct causal variables.

Invariant features matter because environments change

The paper frames causal representations as the abstraction that survives domain shift when superficial correlations do not.

“Causal models can be seen as the correct abstraction level for generalizing across domains.”

This is the core bridge from causal modeling to robust ML. It explains why invariance is the target rather than mere predictive fit.

Toward Causal Representation Learning

Causal models provide the right abstraction for robust, transferable representations — the ICM principle bridges causality and representation learning.
