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.
