Evaluation of Link Prediction performance on a specific co-authorship network graph containing 892 nodes with 50% of values missing, measured using Normalized Squared Frobenius 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 | Link Prediction |
| Dataset (including any stated split) | Network of co-authorship 892 nodes (50% missing values) |
| Metric | Norm. Squared Frobenius Error |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| 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

- [Norm. Squared Frobenius Error](<https://www.sota2.com/research/sota/link-prediction-on-network-of-co-authorship-892-nodes-50-percent-missing-values.md?metric=Norm.%20Squared%20Frobenius%20Error>): Lower is better; unit: SCALAR.
