How this was cleaned
A vision-language model read each image together with its QA and judged the item. The pass is
not a filter that only removes rows — it rewrites answers it finds wrong but salvageable,
drops what it cannot salvage, and adds QA where the image supports more than the source provided.
Each row carries the judge's own record in clean_meta, including the cleaner identity, the
policy it applied, and its per-item scores for legibility, richness and coverage.
A large share of the QA here was written by the cleaning pass, not by the original dataset.
Across the pool that share runs from roughly half to over 80% of a family's turns, and it is
reported in the table above. Those rows have an empty org_answer because no pre-clean original
exists. Treat them as model-generated supervision: they were judged against the image, but they
are not human annotation, and model-written QA is where formatting defects are most likely.
The effect on the answers that were carried over is substantive rather than cosmetic. In this pool the pass corrects values, not just
wording — a curve's critical point restated from 4.00 to 2.00, a computed ratio from 1 to
Approximately 1.33 — and for some families it removed the content entirely, which is why those
families are absent here rather than published empty.
answer vs org_answer
answer— the cleaned answer. Train on this.org_answer— the pre-cleaning answer from the same(image, question)in the uncleaned pool. It is empty for QA the cleaning pass added, which have no original.
For this family
org_answeris empty throughout: recovering it means scanning the whole pre-clean family, which is raw family is 109 GB (> 6 GB cap). The cleanedansweris unaffected.
Where the two differ, the difference is the correction. Keeping both makes every edit auditable instead of asking you to take the cleaning on trust.
Schema
image— HFImage(), renders directly in the dataset viewerimage_sha256— content hash of the imagen_qa— number of turns attached to this imageqa— list of {question,answer,org_answer}, in source orderfamily/clean_meta— provenance and the judge's per-row record
A row with more than one entry in qa is a conversation over a single image, not a set of
independent questions — the turns depend on each other and the image belongs to all of them.
Keep them together and in order when training.
Parquet row groups are written at ~32 MB so the dataset viewer pages without stalling.
What is NOT claimed
No rejection sampling was run against this family: there is no accept/reject verdict per row, and
answer is the cleaned reference rather than a model generation that a string verifier confirmed.
For that, use the *_RS_think / *_rejected datasets in elliot-mllm.
Examples
10 rows taken straight from this dataset. Images are the original files as stored here - no downscaling, no recompression - and every turn is shown in full.
