# IndicSynth-150K

A synthetic document-layout dataset for Indic scripts, generated by the **SA-MCB** engine
(Script-Aware Multi-template Composition Block) for the DocLayout-YOLO-Indic project.

- **150,000 pages** (142,500 train / 7,500 val)
- **9 layout classes**: text_body, headline, table, figure, caption, advertisement, sidebar, pull-quote, decorative-frame
- **11 Noto fonts**, 23 layout templates, 10 Indic scripts + Latin
- Correct Indic shaping via HarfBuzz (conjuncts, stacked matras, shirorekha, RTL for Urdu)

Because each region is placed by the generator, **bounding-box labels are exact and require no manual annotation.**

## Model
Trained checkpoints: [VigneshPR/doclayout-yolo-indic](https://huggingface.co/VigneshPR/doclayout-yolo-indic)

## Note on findings
In the parent project, pretraining on this corpus did **not** improve final accuracy over plain fine-tuning
(a controlled-ablation finding attributed to catastrophic forgetting). The dataset remains useful for
synthetic-data research; see the project for details.
