EML-CD: Causal Mechanism Recovery via EML Symbolic Trees in Structure Learning

arXiv:2606.05942v1 Announce Type: cross Abstract: Neural network (NN)-based nonlinear causal discovery methods recover DAG structure but leave each causal mechanism as a black box. Waxman et al. argued that extracting causal mechanisms from NN weights is ill-posed. We propose EML-CD, a framework that integrates the EML operator (capable of composing elementary functions from a single binary operator) into causal structure learning, with interpretable mechanism recovery as the primary objective. EML-CD represents each edge mechanism as a gated EML binary tree and automatically discovers closed-

Why this matters
Why now

The increasing focus on interpretability and explainability in AI, particularly for causal discovery, is driving innovation in methods that move beyond black-box models.

Why it’s important

This development offers a pathway to more transparent and auditable AI systems, crucial for critical applications and for truly understanding complex relationships extracted by AI.

What changes

AI models for causal discovery may transition from opaque neural networks to interpretable symbolic representations, allowing for direct understanding of causal mechanisms.
