Evaluation of four-class sleep staging performance using the HealthBed Study dataset, reporting metrics including kappa\_mu, kappa\_T, Accuracy\_mu, and Accuracy\_T.

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 | four-class sleep staging |
| Dataset (including any stated split) | HealthBed Study |
| Metric | Kappa (mu) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 1 of 1 |
| 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

- [Kappa (mu)](<https://www.sota2.com/research/sota/four-class-sleep-staging-on-healthbed-study.md?metric=Kappa%20(mu)>): Higher is better; unit: SCALAR.

- [Kappa (T)](<https://www.sota2.com/research/sota/four-class-sleep-staging-on-healthbed-study.md?metric=Kappa%20(T)>): Higher is better; unit: SCALAR.

- [Accuracy (mu)](<https://www.sota2.com/research/sota/four-class-sleep-staging-on-healthbed-study.md?metric=Accuracy%20(mu)>): Higher is better; unit: PERCENT.

- [Accuracy (T)](<https://www.sota2.com/research/sota/four-class-sleep-staging-on-healthbed-study.md?metric=Accuracy%20(T)>): Higher is better; unit: PERCENT.
