Evaluation of models for assessing surgical skills specifically for Knot Tying using the JIGSAWS dataset under a Leave-One-Subject-Out (LOSO) cross-validation scheme, reporting Spearman's Correlation Coefficient (SSC) and Mean Absolute Error (MAE).

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 | Surgical Skill Assessment (Knot Tying) |
| Dataset (including any stated split) | JIGSAWS (LOSO) |
| Metric | Spearman's Correlation Coefficient |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| 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

- [Spearman's Correlation Coefficient](<https://www.sota2.com/research/sota/surgical-skill-assessment-knot-tying-on-jigsaws-loso.md?metric=Spearman%27s%20Correlation%20Coefficient>): Higher is better; unit: SCALAR.

- [Mean Absolute Error](<https://www.sota2.com/research/sota/surgical-skill-assessment-knot-tying-on-jigsaws-loso.md?metric=Mean%20Absolute%20Error>): Lower is better; unit: SCALAR.
