Evaluation of models predicting the quality scores (MAE, RMSE, Pearson's r) of machine translation outputs on the FLORES-AE33 Type II 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 | Translation Score Prediction |
| Dataset (including any stated split) | FLORES-AE33 (Type II) |
| Metric | MAE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 8 of 8 |
| 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/translation-score-prediction-on-flores-ae33-type-ii.md?metric=MAE>): Lower is better; unit: SCALAR.

- [RMSE](<https://www.sota2.com/research/sota/translation-score-prediction-on-flores-ae33-type-ii.md?metric=RMSE>): Lower is better; unit: SCALAR.

- [Pearson's r](<https://www.sota2.com/research/sota/translation-score-prediction-on-flores-ae33-type-ii.md?metric=Pearson%27s%20r>): Higher is better; unit: SCALAR.
