| # Reproducing Pointerbench-Sheets |
|
|
| The benchmark is generated programmatically from the |
| `spreadsheet-coordinate-grounding` generator in the source repository. |
|
|
| ```bash |
| # from the generator directory in the source repo: |
| python3 build_pointerbench.py --n 500 --seed 90111 --out /path/to/pointerbench-sheets |
| ``` |
|
|
| - **Seed `90111`** is disjoint from the training-data seed (`7`), so every |
| benchmark sheet is unseen during training. |
| - The build renders one distinct sheet per example, saves it as |
| `data/test/<i>.png`, and writes one `data/test/metadata.jsonl` row with the |
| instruction, the pixel `bbox`, the center `point`, and the category / UI-style |
| / language tags. |
| - The benchmark includes ordinary object-like targets (cells, headers, colored |
| regions) plus thin spreadsheet edge targets: column resize handles, row resize |
| handles, right cell edges, bottom cell edges, and the four corners of visible |
| cells. It also includes relative-navigation tasks such as "three rows below |
| A5" and "two columns right and one row down from B7". |
| - Rendering is fully deterministic given the seed (pure PIL), so the box |
| coordinates are pixel-exact and the set is byte-reproducible. |
|
|
| Regenerating with the same seed reproduces the identical 500 examples. To grow |
| or refresh the set, change `--n` / `--seed` and bump the dataset version. |
