arXiv:2605.21288v1 Announce Type: new Abstract: Tabular foundation models with different architectures converge in accuracy across a range of classification and regression tasks. This raises questions a leaderboard cannot answer: (i) whether the models execute the same in-context algorithm, (ii) where row, column, and class-permutation invariances originate, and (iii) how robust they are under perturbations engineered against the inferred mechanism. We characterize all three. The model families realize qualitatively distinct similarity-based readouts: from an attention-weighted vote over conte
The proliferation of AI models demands deeper understanding of their internal mechanisms for responsible and effective deployment. This paper provides foundational research into tabular foundation models.
Understanding the mechanistic behavior of AI models is crucial for improving their reliability, robustness, and interpretability across critical applications. This contributes to demystifying AI's black box.
The focus shifts from merely achieving high accuracy to comprehensively understanding model internal workings, leading to more robust and explainable AI systems. This publication highlights the ongoing efforts to open the black box of tabular AI models.
