| # Cleaned-PlotQA v2 with difficulty tiers (vectorized + calibrated) | |
| This repository augments jrc/cleaned-plotqa-v2 by adding a single column difficulty_tier ∈ {easy, medium, hard} computed with a vectorized, batch‑scored rule set and cutoffs calibrated on a 1,000‑example sample to avoid tier collapse. | |
| ## Tier counts | |
| - easy: 77403 | |
| - medium: 78521 | |
| - hard: 43369 | |
| - total labeled: 199293 | |
| ## Notes | |
| - Only one new column is added; original fields remain unchanged. | |
| - The scoring runs batched (8192) with multiprocessing (num_proc=4) for speed; adjust to fit memory/CPU limits. | |
