Evaluation of model attribution quality on the test split of the TITAN one-step t+1 dataset, measured using metrics such as Sparsity (Gini), Faithfulness (ROAD), and LLE measures.

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 | Attribution Quality Evaluation |
| Dataset (including any stated split) | TITAN one-step t+1 (test) |
| Metric | Sparsity (Gini) |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 6 of 6 |
| 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

- [Sparsity (Gini)](<https://www.sota2.com/research/sota/attribution-quality-evaluation-on-titan-one-step-t-plus-1-test.md?metric=Sparsity%20(Gini)>): Higher is better; unit: SCALAR.

- [Faithfulness (ROAD)](<https://www.sota2.com/research/sota/attribution-quality-evaluation-on-titan-one-step-t-plus-1-test.md?metric=Faithfulness%20(ROAD)>): Higher is better; unit: SCALAR.

- [LLE (L2)](<https://www.sota2.com/research/sota/attribution-quality-evaluation-on-titan-one-step-t-plus-1-test.md?metric=LLE%20(L2)>): Lower is better; unit: SCALAR.

- [LLE (Cosine)](<https://www.sota2.com/research/sota/attribution-quality-evaluation-on-titan-one-step-t-plus-1-test.md?metric=LLE%20(Cosine)>): Lower is better; unit: SCALAR.
