Evaluation of Chord Recognition performance on the validation split of the uspop2002 dataset, specifically using the 25-label major/minor vocabulary, measured by Root and Maj-min accuracy.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Chord Recognition |
| Dataset (including any stated split) | uspop2002 25-label maj-min vocabulary (val) |
| Metric | Root Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Root Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-uspop2002-25-label-maj-min-vocabulary-val.md?metric=Root%20Accuracy>): Higher is better; unit: PERCENT.

- [Maj-min Accuracy](<https://www.sota2.com/research/sota/chord-recognition-on-uspop2002-25-label-maj-min-vocabulary-val.md?metric=Maj-min%20Accuracy>): Higher is better; unit: PERCENT.
