# Outlier Detection on optdigits ADBench Source: [Outlier Detection on optdigits ADBench]() Collection index: [llms.txt]() Data updated: 2026-03-17T07:10:24.442Z Evaluation of Outlier Detection performance on the optdigits ADBench dataset, reporting AUROC and AUPRC. 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 | Outlier Detection | | Dataset (including any stated split) | optdigits ADBench | | Metric | AUROC | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 17 of 17 | | 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 - [AUROC](): Higher is better; unit: PERCENT. - [AUPRC](): Higher is better; unit: PERCENT. ## Recorded results | Method | AUROC | Result date | Report paper | | --- | --- | --- | --- | | MetaOD | 87.22 | Not recorded | 68fa79e91e209131cea7feaf | | UniOD | 73.8 | Not recorded | 68fa79e91e209131cea7feaf | | NeutralAD | 69.38 | Not recorded | 68fa79e91e209131cea7feaf | | IF | 68.72 | Not recorded | 68fa79e91e209131cea7feaf | | ECOD | 60.45 | Not recorded | 68fa79e91e209131cea7feaf | | KPCA+MLP | 56.63 | Not recorded | 68fa79e91e209131cea7feaf | | SLAD | 55.29 | Not recorded | 68fa79e91e209131cea7feaf | | ICL | 54.18 | Not recorded | 68fa79e91e209131cea7feaf | | LODA | 52.42 | Not recorded | 68fa79e91e209131cea7feaf | | OC-SVM | 51.78 | Not recorded | 68fa79e91e209131cea7feaf | | DPAD | 50.63 | Not recorded | 68fa79e91e209131cea7feaf | | AE | 45.11 | Not recorded | 68fa79e91e209131cea7feaf | | DSVDD | 40.74 | Not recorded | 68fa79e91e209131cea7feaf | | kNN | 39.91 | Not recorded | 68fa79e91e209131cea7feaf | | LOF | 39.03 | Not recorded | 68fa79e91e209131cea7feaf | | DTE-NP | 36.38 | Not recorded | 68fa79e91e209131cea7feaf | | KDE | 32.32 | Not recorded | 68fa79e91e209131cea7feaf | ### MetaOD AUROC: 87.22.
