# jp-systemsx-ndcg

> Metric `JP-SystemsX/nDCG` from the HuggingFace `evaluate` library.

## When to invoke

User asks to compute `JP-SystemsX/nDCG` or wants HF evaluate's canonical version.

## Recipe

```python
import evaluate
metric = evaluate.load("JP-SystemsX/nDCG")
result = metric.compute(predictions=preds, references=refs)
print(result)
```

## Don'ts

- Don't assume your in-house `JP-SystemsX/nDCG` matches HF — version conventions vary.
- Many evaluate metrics have task-specific arguments (`average=`, `lang=`, `model_type=`); read the metric card before reporting numbers.
