Privacy Vulnerabilities of Attention Layers in Tabular Foundation Models and Protection of High-Risk Queries

Researchers demonstrate that transformer-based tabular foundation models leak sensitive information through their attention mechanisms, enabling effective membership inference attacks despite being pre-trained on synthetic data. The study proposes both an attack method (AMIA) and a defense strategy inspired by k-anonymity that reduces privacy leakage by 50% while maintaining model performance.

GOTabPFN: From Feature Ordering to Compact Tokenization for Tabular Foundation Models on High-Dimensional Data

Researchers introduce GOTabPFN, a novel approach for applying tabular foundation models to high-dimensional, low-sample-size datasets without retraining large models. The method combines Graph-guided Ordering with Local Refinement (GO-LR) and Neuro-Inspired Subunit Compression (NSC) to create compact token representations, improving prediction accuracy and stability under constrained computational budgets.

Is One Layer Enough? Understanding Inference Dynamics in Tabular Foundation Models

Researchers conducted the first large-scale mechanistic study of tabular foundation models, revealing significant redundancy across inference layers. They demonstrated that a single-layer looped model can match performance of state-of-the-art models while using only 20% of the parameters, challenging assumptions about depth requirements in transformer architectures.
