Evaluation of Hyperspectral Unmixing performance on the Samson dataset, measured using component-wise Spectral Angle Distance (SAD) for Soil, Tree, and Water, along with the overall Mean SAD.

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 | Hyperspectral Unmixing |
| Dataset (including any stated split) | Samson |
| Metric | SAD (Soil) |
| Unit | SCALAR |
| Direction | Lower 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

- [SAD (Soil)](<https://www.sota2.com/research/sota/hyperspectral-unmixing-on-samson-component-sad-and-mean-sad.md?metric=SAD%20(Soil)>): Lower is better; unit: SCALAR.

- [SAD (Tree)](<https://www.sota2.com/research/sota/hyperspectral-unmixing-on-samson-component-sad-and-mean-sad.md?metric=SAD%20(Tree)>): Lower is better; unit: SCALAR.

- [SAD (Water)](<https://www.sota2.com/research/sota/hyperspectral-unmixing-on-samson-component-sad-and-mean-sad.md?metric=SAD%20(Water)>): Lower is better; unit: SCALAR.

- [Mean SAD](<https://www.sota2.com/research/sota/hyperspectral-unmixing-on-samson-component-sad-and-mean-sad.md?metric=Mean%20SAD>): Lower is better; unit: SCALAR.
