The Good, the Bad, and the Ugly of Markov Boundary for Tabular Prediction

arXiv:2605. 29411v2 Announce Type: replace-cross Abstract: Under standard graphical assumptions, the Markov boundary of a target variable is the smallest set of features that renders every other feature redundant.

Xiaomi-TabLDM: A Tabular Foundation Model Technical Report

Xiaomi-TabLDM is a tabular foundation model that performs classification and regression via in-context learning without task‑specific fine‑tuning. It is pretrained solely on synthetic data from structural causal models, achieving top‑ranked regression results on multiple benchmarks while reducing training and prediction time compared to leading models. The architecture incorporates a three‑stage training strategy, dual‑stream feature grouping, lightweight attention residuals, and sparse mixture‑of‑experts, and it can further improve accuracy through test‑time compute scaling.

EXAONE Tabular 1.0 : Technical Report

EXAONE Tabular 1.0 is a compact tabular foundation model family that performs classification and regression via in-context learning without dataset-specific gradient updates. It is pretrained exclusively on a synthetic structural‑causal‑model prior and introduces an architecture‑centered redesign that interleaves feature‑axis and item‑axis attention within each Transformer layer, mediated by summary tokens. Across four public benchmarks, its 20.81 M‑parameter classification model ranks first on TabArena, surpassing tuned ensembles and AutoML pipelines, while its regression model matches the performance of a 1.64 B‑parameter model at roughly one‑eleventh the inference cost, and it achieves top rankings on BCCO, TALENT, and ScoringBench.

LLMs on Tabular Data with Limited Semantics: Evidence from Industrial Car Retrofit Prediction

arXiv:2606. 15314v1 Announce Type: cross Abstract: Industrial retrofit planning depends on structured operational data rather than free text: planners must estimate whether a newly registered prototype will require a retrofit, which retrofit package it will need, and how long the work will take.

When Tabular Foundation Models Transfer Across Modalities: A Systematic Evaluation Across 95 Datasets, 7 Modalities, and Two Regimes

arXiv:2606. 02106v1 Announce Type: new Abstract: We present a single classification pipeline that combines an Equiangular Tight Frame (ETF) preprocessing stage with a tabular foundation model for in-context inference, applied identically across modalities once data is mapped to fixed vector representations.

TabPFN-3.5: Technical Report

The report introduces TabPFN‑3.5, a new flagship tabular foundation model that outperforms its predecessor TabPFN‑3 and all existing baselines on a wide range of tabular tasks. It achieves state‑of‑the‑art performance on standard tabular prediction in TabArena and extends to practical scenarios such as non‑i.i.d. data, temporal or grouped splits, tables containing strings, text, images, high‑cardinality categorical features, and wide tables. Variants like TabPFN‑3.5‑Fast, TabPFN‑3.5‑Plus, and TabPFN‑3.5‑Thinking offer faster inference, expanded multimodal capabilities, and further speed improvements up to 12× faster than the previous Thinking mode.
