Evaluation of fundus image grading performance on the target-imbalanced split of the APTOS dataset, reporting metrics including Overall Accuracy (OA), Mean Accuracy (mAcc), F1-score, and 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 | Fundus image grading |
| Dataset (including any stated split) | APTOS Target-imbalanced |
| Metric | OA |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [OA](<https://www.sota2.com/research/sota/fundus-image-grading-on-aptos-target-imbalanced.md?metric=OA>): Higher is better; unit: PERCENT.

- [mAcc](<https://www.sota2.com/research/sota/fundus-image-grading-on-aptos-target-imbalanced.md?metric=mAcc>): Higher is better; unit: PERCENT.

- [F1](<https://www.sota2.com/research/sota/fundus-image-grading-on-aptos-target-imbalanced.md?metric=F1>): Higher is better; unit: PERCENT.

- [MAE](<https://www.sota2.com/research/sota/fundus-image-grading-on-aptos-target-imbalanced.md?metric=MAE>): Lower is better; unit: SCALAR.
