Are Tabular Foundation Models Robust to Realistic Query Distribution Shifts in Microbiome Data?
Researchers benchmarked tabular foundation models (TFMs) on microbiome data to test their robustness against realistic distribution shifts, finding that all models degrade significantly under perturbations even when key discriminative features are preserved. The study reveals that TFMs are particularly vulnerable to zero-inflation shifts and global feature structure corruption, suggesting current foundation model architectures may struggle with real-world data variability in biological applications.
