# Clustering Improvement on Single-cell datasets Source: [Clustering Improvement on Single-cell datasets]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:36:19.146Z Evaluation of clustering performance improvement on Single-cell datasets, measured using Average Rank metrics for Normalized Mutual Information (NMI) and Purity. 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 | Clustering improvement | | Dataset (including any stated split) | Single-cell datasets | | Metric | Avg Rank (NMI) | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 27 of 27 | | 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 - [Avg Rank (NMI)](): Lower is better; unit: SCALAR. - [Avg Rank (Purity)](): Lower is better; unit: SCALAR. ## Recorded results | Method | Avg Rank (NMI) | Result date | Report paper | | --- | --- | --- | --- | | Var. of Compression | 2.111 | Not recorded | 68fa72ef1e209131cea595d5 | | Var. of Compression | 2.667 | Not recorded | 68fa72ef1e209131cea595d5 | | Var. of Compression | 2.778 | Not recorded | 68fa72ef1e209131cea595d5 | | LOF + PCA | 3.444 | Not recorded | 68fa72ef1e209131cea595d5 | | ECOD | 3.556 | Not recorded | 68fa72ef1e209131cea595d5 | | ECOD | 3.667 | Not recorded | 68fa72ef1e209131cea595d5 | | LOF | 3.889 | Not recorded | 68fa72ef1e209131cea595d5 | | Isolation Forest + PCA | 4.111 | Not recorded | 68fa72ef1e209131cea595d5 | | Isolation Forest + PCA | 4.111 | Not recorded | 68fa72ef1e209131cea595d5 | | Isolation Forest + PCA | 4.111 | Not recorded | 68fa72ef1e209131cea595d5 | | LOF + PCA | 4.222 | Not recorded | 68fa72ef1e209131cea595d5 | | ECOD + PCA | 4.222 | Not recorded | 68fa72ef1e209131cea595d5 | | KNN | 4.333 | Not recorded | 68fa72ef1e209131cea595d5 | | LOF + PCA | 4.444 | Not recorded | 68fa72ef1e209131cea595d5 | | KNN | 4.556 | Not recorded | 68fa72ef1e209131cea595d5 | | LOF | 4.667 | Not recorded | 68fa72ef1e209131cea595d5 | | KNN | 4.667 | Not recorded | 68fa72ef1e209131cea595d5 | | KNN + PCA | 4.667 | Not recorded | 68fa72ef1e209131cea595d5 | | KNN + PCA | 4.778 | Not recorded | 68fa72ef1e209131cea595d5 | | KNN + PCA | 4.778 | Not recorded | 68fa72ef1e209131cea595d5 | | Isolation Forest | 4.778 | Not recorded | 68fa72ef1e209131cea595d5 | | ECOD | 4.778 | Not recorded | 68fa72ef1e209131cea595d5 | | Isolation Forest | 5.111 | Not recorded | 68fa72ef1e209131cea595d5 | | ECOD + PCA | 5.111 | Not recorded | 68fa72ef1e209131cea595d5 | | LOF | 5.444 | Not recorded | 68fa72ef1e209131cea595d5 | | Isolation Forest | 5.667 | Not recorded | 68fa72ef1e209131cea595d5 | | ECOD + PCA | 6.333 | Not recorded | 68fa72ef1e209131cea595d5 | ### Var. of Compression Avg Rank (NMI): 2.111.
