Evaluation of EEG signal denoising performance using the test split of BCI Competition IV-2a, reporting metrics such as CC, RMSE, T-RRMSE, S-RRMSE, and SDR.

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 Denoising |
| Dataset (including any stated split) | BCI Competition IV-2a (test) |
| Metric | CC |
| Unit | SCALAR |
| 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

- [CC](<https://www.sota2.com/research/sota/eeg-denoising-on-bci-competition-iv-2a-test.md?metric=CC>): Higher is better; unit: SCALAR.

- [RMSE](<https://www.sota2.com/research/sota/eeg-denoising-on-bci-competition-iv-2a-test.md?metric=RMSE>): Lower is better; unit: SCALAR.

- [T-RRMSE](<https://www.sota2.com/research/sota/eeg-denoising-on-bci-competition-iv-2a-test.md?metric=T-RRMSE>): Lower is better; unit: SCALAR.

- [S-RRMSE](<https://www.sota2.com/research/sota/eeg-denoising-on-bci-competition-iv-2a-test.md?metric=S-RRMSE>): Lower is better; unit: SCALAR.

- [SDR](<https://www.sota2.com/research/sota/eeg-denoising-on-bci-competition-iv-2a-test.md?metric=SDR>): Higher is better; unit: SCALAR.
