TabCausal: Pretraining Across Causal Environments for Tabular Causal Discovery

arXiv:2605.31156v1 Announce Type: new Abstract: Causal discovery aims to recover directed causal relations from observational and interventional data, providing a basis for mechanistic understanding and reliable decision-making. Causal discovery foundation models (CDFMs) seek to amortize this problem by mapping a dataset directly to a causal graph in a single forward pass, avoiding per-dataset testing, search, or optimization. However, existing CDFMs remain limited, often failing to consistently match strong classical methods, and we find that a key bottleneck is how causal pretraining tasks a

Why this matters
Why now

The proliferation of AI systems is driving a critical need for explainable and robust decision-making, which causal discovery foundation models aim to address by improving their real-world applicability.

Why it’s important

Improved causal discovery foundation models could significantly enhance the reliability and efficiency of AI, moving beyond mere correlation to provide deeper mechanistic understanding crucial for critical applications.

What changes

Current limitations in causal discovery, such as reliance on per-dataset testing, could be overcome, leading to more generalized and performant AI systems capable of understanding cause and effect.
