The Independent Causal Mechanisms principle: causal generative processes are modular and autonomous

Each mechanism in a causal system operates independently — changing one mechanism does not alter the others.

“The mechanisms of the causal generative model are autonomous and do not inform or influence each other.”

Reasoning

Because: Nature's generative process factorizes into independent modules corresponding to edges in the causal graph. This is a structural assumption about how the world generates data.

Boundaries: ICM is a modeling assumption, not provable from data. In tightly coupled systems, mechanisms may not be cleanly separable.

ICM as the paper's backbone assumption

The paper treats independent causal mechanisms as the structural reason causal representations can generalize.

“The mechanisms of the causal generative model are autonomous and do not inform or influence each other.”

Without an explicit mechanism story, the representation-learning claim collapses back into pattern matching.

Toward Causal Representation Learning

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