Evaluation of EEG classification performance using the Real EEG covariance SPD(22) dataset, specifically utilizing the 27 subject split pairs configuration, reporting Balanced 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 | EEG Classification |
| Dataset (including any stated split) | Real EEG covariance SPD(22) (27 subject split pairs) |
| Metric | Balanced 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

- [Balanced Accuracy](<https://www.sota2.com/research/sota/eeg-classification-on-real-eeg-covariance-spd-22-27-subject-split-pairs.md?metric=Balanced%20Accuracy>): Higher is better; unit: PERCENT.
