Evaluation of models on predicting phase composition using the test split of the COSMO-RS dataset, measured using MAE, RMSE, and R2.

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 | Phase-composition prediction |
| Dataset (including any stated split) | COSMO-RS (test) |
| Metric | MAE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| 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/phase-composition-prediction-on-cosmo-rs-test.md?metric=MAE>): Lower is better; unit: SCALAR.

- [RMSE](<https://www.sota2.com/research/sota/phase-composition-prediction-on-cosmo-rs-test.md?metric=RMSE>): Lower is better; unit: SCALAR.

- [R2](<https://www.sota2.com/research/sota/phase-composition-prediction-on-cosmo-rs-test.md?metric=R2>): Higher is better; unit: PERCENT.
