LED (Box Overlay + JSON) - Element Error F1: leaderboard
Metric: Element-level macro F1 (x 100): labelling each predicted box with one of eight structural error types or none, given the page image with the predicted boxes drawn on it plus the layout JSON (with ground-truth boxes), on LED's 4,996 DocLayNet test pages with structural layout errors (missing, hallucinated, resized, misclassified, split, merged, overlapping, duplicated regions) injected at the rates a commercial layout model produces, zero-shot via OpenRouter at temperature 1.0; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 8 models tracked.
