Evaluation of general classification performance on the UCI Annealing dataset using an 80%:20% train-test split, reporting Classification Error.

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 | Classification |
| Dataset (including any stated split) | UCI Annealing (80%:20% train-test split) |
| Metric | Classification Error |
| Unit | PERCENT |
| Direction | Lower is better |
| Results loaded | 9 of 9 |
| 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

- [Classification Error](<https://www.sota2.com/research/sota/classification-on-uci-annealing-80-percent-20-percent-train-test-split.md?metric=Classification%20Error>): Lower is better; unit: PERCENT.
