Robustness of Tabular Foundation Models Pretrained with Adversarial Noise Distributions

The development of tabular foundation models (TFMs) has accelerated in recent years, showing strong potential to outperform traditional ML methods for structured data. A key finding is that TFMs can be pretrained entirely on synthetic datasets, opening opportunities to design data generators that encourage desirable model properties. Prior work has mainly focused on crafting high-quality priors over generators to improve overall pretraining performance. Our insight is that parameterizing the generator distribution enables an adversarial robustness perspective: during training, we can adapt the

Research goal: To what extent does pretraining tabular foundation models on synthetic data with adversarial noise distributions improve robustness on OOD benchmarks compared to Gaussian noise pretraining?
