Evaluation of facial age estimation performance specifically on the 21-60 year old subset of the UTKFace dataset, typically measured using Mean Absolute Error (MAE).

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 | Age Estimation |
| Dataset (including any stated split) | UTKFace 21-60 years old |
| Metric | MAE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 4 of 4 |
| 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

- [MAE](<https://www.sota2.com/research/sota/age-estimation-on-utkface-21-60-years-old.md?metric=MAE>): Lower is better; unit: SCALAR.
