Evaluation of Lasso regression performance on the Synthetic Lasso Problem dataset configured with dimensionality D=200, measured using Solution time and Relative Error.

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 | Lasso regression |
| Dataset (including any stated split) | Synthetic Lasso Problem D=200 |
| Metric | Solution Time |
| Unit | TIME |
| Direction | Lower is better |
| Results loaded | 7 of 7 |
| 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

- [Solution Time](<https://www.sota2.com/research/sota/lasso-regression-on-synthetic-lasso-problem-d-200.md?metric=Solution%20Time>): Lower is better; unit: TIME.

- [Relative Error](<https://www.sota2.com/research/sota/lasso-regression-on-synthetic-lasso-problem-d-200.md?metric=Relative%20Error>): Lower is better; unit: SCALAR.
