CalArena — Calibration Benchmark Dataset CalArena is a large-scale benchmark for evaluating post-hoc calibration methods on classification models. It covers 7 benchmarks across tabular and computer vision domains, spanning hundreds of (dataset, model) pairs and three problem types (binary, multiclass and large scale multiclass). Each entry in the benchmark is a (p_cal, y_cal, p_test, y_test) tuple — the calibration split and test split of predicted probabilities and ground-truth… See the full description on the dataset page: https://huggingface.co/datasets/probkit/CalArena.
