Evaluation of Intrinsic Dimension Estimation performance on the synthetic MNL2 manifold dataset, where the true dimension is 4 and the sample size is 2000.

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 | Intrinsic Dimension Estimation |
| Dataset (including any stated split) | MNL2 (4) (n=2000) |
| Metric | Mean Dimension Estimate |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 10 of 10 |
| 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

- [Mean Dimension Estimate](<https://www.sota2.com/research/sota/intrinsic-dimension-estimation-on-mnl2-d-4-n-2000.md?metric=Mean%20Dimension%20Estimate>): Higher is better; unit: SCALAR.
