GEAR is a two‑stage framework that distills tabular foundation models into lightweight MLP or tree‑based predictors for efficient CPU deployment. In the first stage, synthetic covariates are used as teacher‑query locations to train the student on soft TFM targets, expanding coverage beyond observed rows. The second stage re‑anchors the student to the target distribution using real labels and out‑of‑fold teacher predictions, preventing self‑labeling leakage and improving performance. Experiments on TALENT and TabArena show that GEAR‑distilled MLPs outperform supervised MLPs by up to 2.00 AUC points on binary tasks and 1.35 on multiclass tasks, and also outperform CatBoost, while dramatically reducing inference time and memory usage.

The paper investigates active in-context learning for Tabular Foundation Models (TFMs), focusing on how different acquisition strategies—diversity, predictive uncertainty, and target-aware information gain—perform as more labeled data is added. It introduces Target-Aware Nearest Neighbor (TANN) and Expected Predictive Information Gain in Context (EPIC) methods, comparing them to classical rules across twenty benchmarks with two TFMs and gradient-boosted decision trees. Key findings include that diversity-based acquisition is most effective early on, target-aware nearest-neighbor labeling significantly improves performance, and EPIC achieves near full-data performance while labeling only 5–10% of the pool.

The paper presents a method for distilling tabular foundation models (TFMs) into lightweight, dataset‑specific students. By using the full labeled training set as teacher context and training students on both observed and synthetic queries, the authors achieve significant performance gains over traditional supervised models on TabArena and TALENT benchmarks. The distilled students also provide substantial inference speedups, reducing the cost of repeated inference.

The paper demonstrates that a tabular foundation model can achieve strong generalization using only a single real table for self‑supervised pre‑training, challenging the belief that large synthetic or real datasets are necessary. By systematically pre‑training and evaluating across diverse benchmarks, the authors show that the number and quality of tasks that can be derived from a dataset are critical for downstream performance. This finding suggests that carefully constructed task sets from limited data can enable effective transfer learning in tabular models.
