Evaluation of model performance on the Matrix Completion task using the canonical 80/20 test split of the Douban dataset, typically measured by Root Mean Squared Error (RMSE).

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 | Matrix Completion |
| Dataset (including any stated split) | Douban canonical 80/20 (test) |
| Metric | RMSE |
| 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

- [RMSE](<https://www.sota2.com/research/sota/matrix-completion-on-douban-canonical-80-20-test.md?metric=RMSE>): Lower is better; unit: SCALAR.
