SketchDUO

This dataset contains sketch images with optional captions and optional question-answer pairs.

Structure

Splits: positive, negative
Each row contains:
- image
- caption
- qa_pairs
- has_caption
- has_qa

Notes

All image files under each split are uploaded as rows.
When a caption or QA annotation is missing for an image, the corresponding field is left empty.
Rows without captions correspond to augmented data.
QA pairs are grouped per image into the qa_pairs column.

Counts

Total rows: 35851
Rows with captions: 4693
Rows with QA: 4692
Image-only rows: 31158

Split counts

positive: 24000 rows
negative: 11851 rows
