Evaluation of performance on the Heterogeneous material learning task using the test split of the Mechanical MNIST OOD heterogeneous material 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 | Heterogeneous material learning |
| Dataset (including any stated split) | Mechanical MNIST OOD heterogeneous material (test) |
| Metric | Test Error |
| Unit | PERCENT |
| Direction | Lower 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

- [Test Error](<https://www.sota2.com/research/sota/heterogeneous-material-learning-on-mechanical-mnist-ood-heterogeneous-material-test.md?metric=Test%20Error>): Lower is better; unit: PERCENT.
