EpiCurveBench: leaderboard
Metric: EpiCurveSimilarity, ECS (%): edit distance with real penalty between each extracted and ground-truth series (gap penalty 1, value differences normalized by the y-axis range and counted fully above 1%), scaled to 0-100 and averaged over matched series per chart (0 for a missed series), then over the 1,000 real-world epidemic curve images; the model returns the chart data as a TSV from one generic extraction prompt; the general-purpose VLMs at high reasoning effort, the specialized chart extractors in their single configuration; higher is better. Source: arxiv.org. Saturation forecast: Around February 2028. 6 models tracked.
