Evaluation of Referring Expression Generation performance on the specific 'U' subset of the validation split of the RefCOCOg dataset.

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 | Referring Expression Generation |
| Dataset (including any stated split) | RefCOCOg U (val) |
| Metric | Score |
| Unit | PERCENT |
| Direction | Higher 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

- [Score](<https://www.sota2.com/research/sota/referring-expression-generation-on-refcocog-u-val.md?metric=Score>): Higher is better; unit: PERCENT.
