Evaluation of Matrix Completion performance on the specific canonical 80/20 test split of the Flixster dataset, utilizing RMSE metrics derived from user-only and combined user/item graph configurations.

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) | Flixster canonical 80/20 (test) |
| Metric | RMSE (user graph only) |
| 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 (user graph only)](<https://www.sota2.com/research/sota/matrix-completion-on-flixster-canonical-80-20-test.md?metric=RMSE%20(user%20graph%20only)>): Lower is better; unit: SCALAR.

- [RMSE (user/item graphs)](<https://www.sota2.com/research/sota/matrix-completion-on-flixster-canonical-80-20-test.md?metric=RMSE%20(user%2Fitem%20graphs)>): Lower is better; unit: SCALAR.
