TFM-Retouche: A Lightweight Input-Space Adapter for Tabular Foundation Models

A new lightweight input-space adapter named TFM-Retouche has been introduced for tabular foundation models (TFMs) such as TabPFN-2.6 and TabICLv2. This adapter is designed to learn a small residual correction in the input space, allowing for better alignment of input data with the inductive biases of pretrained models without the need for full fine-tuning or architecture-specific tuning methods.
