# Continual Clustering on Letter Source: [Continual Clustering on Letter]() Collection index: [llms.txt]() Data updated: 2026-05-12T09:23:20.479Z Evaluation of continual clustering performance on the Letter dataset, reporting Average Incremental (AI) and Backward Transfer (BWT) metrics for Adjusted Rand Index (ARI) and Normalized Mutual Information (NMI). 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 | Continual Clustering | | Dataset (including any stated split) | Letter | | Metric | AI NMI | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 15 of 15 | | 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 - [AI NMI](): Higher is better; unit: PERCENT. - [AI ARI](): Higher is better; unit: PERCENT. - [BWT NMI](): Higher is better; unit: SCALAR. - [BWT ARI](): Higher is better; unit: SCALAR. ## Recorded results | Method | AI NMI | Result date | Report paper | | --- | --- | --- | --- | | SOINN+ | 57.1 | Not recorded | 68fa6f2e1e209131cea444b1 | | TCA | 56.5 | Not recorded | 68fa6f2e1e209131cea444b1 | | CAE | 49.4 | Not recorded | 68fa6f2e1e209131cea444b1 | | SOINN+ | 48.9 | Not recorded | 6a02b434dbc836b87d824822 | | CAEA | 48.2 | Not recorded | 68fa6f2e1e209131cea444b1 | | CAEA | 47.3 | Not recorded | 68fa6f2e1e209131cea444b1 | | IDAT | 46.7 | Not recorded | 6a02b434dbc836b87d824822 | | CAE | 46 | Not recorded | 6a02b434dbc836b87d824822 | | ASOINN | 44.1 | Not recorded | 68fa6f2e1e209131cea444b1 | | PHIDA | 43.1 | Not recorded | 6a02b434dbc836b87d824822 | | GNG | 42.7 | Not recorded | 6a02b434dbc836b87d824822 | | CAEA | 38.2 | Not recorded | 6a02b434dbc836b87d824822 | | ASOINN | 36.5 | Not recorded | 68fa6f2e1e209131cea444b1 | | DDVFA | 14.3 | Not recorded | 6a02b434dbc836b87d824822 | | TCA | 4.8 | Not recorded | 68fa6f2e1e209131cea444b1 | ### SOINN+ AI NMI: 57.1.
