Evaluation of model performance on open-set knowledge retrieval using the T-REx (UHN) dataset, typically measured by Macro-averaged EM.

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 | Open-set knowledge retrieval |
| Dataset (including any stated split) | T-REx (UHN) |
| Metric | Macro EM |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 19 of 19 |
| 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

- [Macro EM](<https://www.sota2.com/research/sota/open-set-knowledge-retrieval-on-t-rex-uhn.md?metric=Macro%20EM>): Higher is better; unit: SCALAR.
