# Categorical Data Imputation on letter (test) Source: [Categorical Data Imputation on letter (test)]() Collection index: [llms.txt]() Data updated: 2026-07-09T07:01:53.521Z Evaluation of model performance for Categorical Data Imputation using the test split of the Letter dataset, measured using PFC. 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 | Categorical Data Imputation | | Dataset (including any stated split) | letter (test) | | Metric | PFC | | Unit | PERCENT | | Direction | Higher 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 - [PFC](): Higher is better; unit: PERCENT. ## Recorded results | Method | PFC | Result date | Report paper | | --- | --- | --- | --- | | TDM | 87.2 | Not recorded | 6a4f2b1f32fb937314875c5f | | MIRACLE | 85.07 | Not recorded | 6a4f2b1f32fb937314875c5f | | GAIN | 84.87 | Not recorded | 6a4f2b1f32fb937314875c5f | | MICE | 82.45 | Not recorded | 6a4f2b1f32fb937314875c5f | | KNNImpute | 78.98 | Not recorded | 6a4f2b1f32fb937314875c5f | | IGRM | 77.93 | Not recorded | 6a4f2b1f32fb937314875c5f | | TabCSDI | 77.7 | Not recorded | 6a4f2b1f32fb937314875c5f | | MissForest | 77.42 | Not recorded | 6a4f2b1f32fb937314875c5f | | GRAPE | 77.18 | Not recorded | 6a4f2b1f32fb937314875c5f | | Mean/Mode | 76.9 | Not recorded | 6a4f2b1f32fb937314875c5f | | MIWAE | 76.63 | Not recorded | 6a4f2b1f32fb937314875c5f | | ReMasker | 75.24 | Not recorded | 6a4f2b1f32fb937314875c5f | | DiffPuter | 75.21 | Not recorded | 6a4f2b1f32fb937314875c5f | | OTImpute | 74.89 | Not recorded | 6a4f2b1f32fb937314875c5f | | GCImpute | 74.38 | Not recorded | 6a4f2b1f32fb937314875c5f | | CAGI | 73.33 | Not recorded | 6a4f2b1f32fb937314875c5f | ### TDM PFC: 87.2.
