Evaluation of model performance on predicting chemical mixture proportions using the SMELLNET-MIXTURE (unseen) dataset, measured by KL divergence, MAE, and Cosine similarity.

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 | Mixture proportion prediction |
| Dataset (including any stated split) | SMELLNET-MIXTURE (unseen) |
| Metric | KL Divergence |
| 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

- [KL Divergence](<https://www.sota2.com/research/sota/mixture-proportion-prediction-on-smellnet-mixture-unseen.md?metric=KL%20Divergence>): Lower is better; unit: SCALAR.

- [MAE](<https://www.sota2.com/research/sota/mixture-proportion-prediction-on-smellnet-mixture-unseen.md?metric=MAE>): Lower is better; unit: SCALAR.

- [Cosine Similarity](<https://www.sota2.com/research/sota/mixture-proportion-prediction-on-smellnet-mixture-unseen.md?metric=Cosine%20Similarity>): Higher is better; unit: SCALAR.
