| # 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. |
