Evaluation of Image Classification performance on the test split of the PneumoniaMNIST dataset configured with alpha=0.1 (Severe Non-IID distribution), reporting Accuracy, Macro-F1, and Expected Calibration Error (ECE).

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 | Image Classification |
| Dataset (including any stated split) | PneumoniaMNIST alpha = 0.1 (Severe Non-IID) (test) |
| Metric | Accuracy |
| Unit | PERCENT |
| Direction | Higher 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

- [Accuracy](<https://www.sota2.com/research/sota/image-classification-on-pneumoniamnist-alpha-0-1-severe-non-iid-test.md?metric=Accuracy>): Higher is better; unit: PERCENT.

- [Macro-F1](<https://www.sota2.com/research/sota/image-classification-on-pneumoniamnist-alpha-0-1-severe-non-iid-test.md?metric=Macro-F1>): Higher is better; unit: PERCENT.

- [ECE](<https://www.sota2.com/research/sota/image-classification-on-pneumoniamnist-alpha-0-1-severe-non-iid-test.md?metric=ECE>): Lower is better; unit: PERCENT.
