# Data Imputation on california (test) Source: [Data Imputation on california (test)]() Collection index: [llms.txt]() Data updated: 2026-07-09T07:01:53.687Z Evaluation of data imputation performance on the test split of the California dataset, measured using 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 | Data Imputation | | Dataset (including any stated split) | california (test) | | Metric | RMSE | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 16 of 16 | | 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](): Lower is better; unit: SCALAR. ## Recorded results | Method | RMSE | Result date | Report paper | | --- | --- | --- | --- | | MIWAE | 0.141 | Not recorded | 6a4f2b1f32fb937314875c5f | | DiffPuter | 0.1415 | Not recorded | 6a4f2b1f32fb937314875c5f | | GRAPE | 0.1441 | Not recorded | 6a4f2b1f32fb937314875c5f | | GCImpute | 0.1442 | Not recorded | 6a4f2b1f32fb937314875c5f | | ReMasker | 0.1455 | Not recorded | 6a4f2b1f32fb937314875c5f | | CAGI | 0.1489 | Not recorded | 6a4f2b1f32fb937314875c5f | | MissForest | 0.1531 | Not recorded | 6a4f2b1f32fb937314875c5f | | TabCSDI | 0.1551 | Not recorded | 6a4f2b1f32fb937314875c5f | | IGRM | 0.1578 | Not recorded | 6a4f2b1f32fb937314875c5f | | Mean/Mode | 0.1628 | Not recorded | 6a4f2b1f32fb937314875c5f | | MIRACLE | 0.1632 | Not recorded | 6a4f2b1f32fb937314875c5f | | KNNImpute | 0.1645 | Not recorded | 6a4f2b1f32fb937314875c5f | | OTImpute | 0.1796 | Not recorded | 6a4f2b1f32fb937314875c5f | | MICE | 0.1945 | Not recorded | 6a4f2b1f32fb937314875c5f | | GAIN | 0.212 | Not recorded | 6a4f2b1f32fb937314875c5f | | TDM | 0.2121 | Not recorded | 6a4f2b1f32fb937314875c5f | ### MIWAE RMSE: 0.141.
