Evaluation of model confidence estimation performance on the Bios dataset using a freeform tagging methodology, reporting metrics like BS, ECE-M, and SC.

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 | Confidence Estimation (Freeform Tagging) |
| Dataset (including any stated split) | Bios |
| Metric | Brier Score (BS) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| 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

- [Brier Score (BS)](<https://www.sota2.com/research/sota/confidence-estimation-freeform-tagging-on-bios.md?metric=Brier%20Score%20(BS)>): Lower is better; unit: SCALAR.

- [Expected Calibration Error (ECE-M)](<https://www.sota2.com/research/sota/confidence-estimation-freeform-tagging-on-bios.md?metric=Expected%20Calibration%20Error%20(ECE-M)>): Lower is better; unit: SCALAR.

- [Calibration Score (SC)](<https://www.sota2.com/research/sota/confidence-estimation-freeform-tagging-on-bios.md?metric=Calibration%20Score%20(SC)>): Higher is better; unit: SCALAR.
