POLARIS-53K, label-repaired 49,289 of the 53,291 rows in POLARIS-Project/Polaris-Dataset-53K, with 4,580 stored answers corrected and 4,002 rows removed as unrepairable. Measurements on the source set put its bad-label rate at roughly 15.9% [14.3, 17.6] (two independent detectors agreeing on a 2,000-row sample). Mislabelled rows are not uniformly distributed: they concentrate in the problems models fail, which is exactly where a difficulty-calibration pipeline looks.… See the full description on the dataset page: https://huggingface.co/datasets/joanvelja/polaris-53k-repaired.
