# Tibetan Script Classification Benchmark

Holdout benchmark for 6-class Tibetan script classification. **Test split only** — not used during training.
All images are BDRC manuscript page scans, balanced by subclass.

| Class | Images | Subclasses |
|-------|-------:|-----------|
| **Danyig** | 60 | DraDring: 25, DraRing: 9, Drathung: 17, Gongshabma: 3, Tsegdrig: 6 |
| **Druma** | 60 | Dhumri: 22, DruDring: 20, DruRing: 10, Druchen: 2, Druthung: 6 |
| **Gyuyig** | 60 | Khyuyig: 31, Tsumachug: 15, Yigchung: 14 |
| **Pedri** | 60 | Peri: 44, Petsuk: 16 |
| **Tsugdri** | 60 | Trinyig: 36, Tsugchung: 14, Tsugthung: 10 |
| **Uchen** | 60 | Uchen SugDring: 53, Uchen SugRing: 3, Uchen Sugthung: 4 |
| **multiscript** | 60 | Multi-Scripts: 60 |
| **non_tibetan** | 60 | Other: 60 |

**Total: 480 images** across 8 classes.

## Parquet schema

| Column | Type | Description |
|--------|------|-------------|
| `id` | string | BDRC page id (e.g. `W00KG09391-I00KG093950005`) |
| `image_bytes` | binary | JPEG/PNG page image |
| `script` | string | One of: `Danyig`, `Druma`, `Gyuyig`, `Pedri`, `Tsugdri`, `Uchen`, `multiscript`, `non_tibetan` |
| `script_type` | string | Sub-script / subclass name (e.g. `DraDring`, `Multi-Scripts`, `Other`) |

## Load in Python

```python
from datasets import load_dataset

ds = load_dataset("BDRC/tibetan-script-classification-benchmark", split="test")
print(len(ds))  # 480

row = ds[0]
# row["id"], row["image_bytes"], row["script"]
```

## Evaluate a model

```python
from experiments.benchmark_eval.eval import run_benchmark
run_benchmark(model, repo_id="BDRC/tibetan-script-classification-benchmark")
```
