ScoringBench: A Benchmark for Evaluating Tabular Foundation Models with Proper Scoring Rules

ScoringBench is an open, extensible benchmark that evaluates tabular regression models using a comprehensive set of proper scoring rules—such as weighted CRPS, energy scores, and interval scores—alongside traditional point metrics like RMSE. It covers 101 datasets from diverse domains and offers two ranking protocols: an ordinal Demsar/autorank approach and a magnitude‑preserving z‑score ranking. Experiments show that model rankings vary with the chosen scoring rule, revealing that evaluation metric selection is a core modeling decision, especially when different error types have varying consequences.

TabReliBench: Evaluating Tabular Foundation Models Beyond Predictive Accuracy

TabReliBench evaluates tabular foundation models (TFMs) on reliability metrics beyond predictive accuracy, including point prediction, distributional quality, marginal and subgroup calibration, and interval efficiency. The benchmark reveals that TFMs’ performance rankings differ from those in TabArena and vary across reliability measures. While regression TFMs often achieve near‑nominal marginal coverage with narrow intervals, this does not guarantee valid conditional coverage, and ensembling or conformal post‑processing does not consistently improve calibration. The study underscores the need for multidimensional evaluation when selecting reliable TFMs.

Lost in Aggregation: How Benchmarks Overlook Irreplaceable Model Strengths

The paper argues that typical tabular machine learning benchmarks, which aggregate results by averaging scores or ranks, can hide which models are essential for achieving the best performance on specific datasets. It proposes evaluating models against a data‑centric peak performance frontier, classifying them as irreplaceable, sufficient, redundant, or fallible based on their position relative to other models. Applying this to the TabArena benchmark shows that common aggregation metrics mainly capture consistency and failure avoidance, but fail to reflect dataset‑specific strengths, leading to a misalignment between aggregate rewards and true model utility.

Aggregate-then-Calibrate for Human-centered Assessment with Theoretical Guarantees

Human-centered assessment tasks, which are essential for systematic decision-making, rely heavily on human judgment and typically lack verifiable ground truth. Existing approaches face a dilemma: methods using only human judgments suffer from heterogeneous expertise and inconsistent rating scales, while methods using only model-generated scores must learn from imperfect proxies or incomplete features.

Balance of Benchmarks: Semantic Density Reweighting for Task-Conditioned Model Comparison

The paper introduces Balance of Benchmarks (BoB), a framework that improves task-conditioned model comparison by weighting benchmark evidence based on semantic density, equating scores across varying difficulty levels, and pooling task-relevant residuals. BoB retains all eligible benchmark data while adjusting its influence, outperforming uniform averaging on the WildScores dataset with higher Spearman correlation, lower MAE, and better shortlist hit rates. The method also reduces ranking instability when benchmarks are repeated or paraphrased, and lowers retrospective regret in model selection.

Coresets Before Score Sets: Evaluation-Unsupervised Prompt Subset Selection for LLM Benchmarks
