# Unsupervised Image Classification on ImageNet 200 randomly selected classes (val) Source: [Unsupervised Image Classification on ImageNet 200 randomly selected classes (val)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:06:36.851Z Evaluation of unsupervised image classification performance on a specific subset of 200 randomly selected classes from the ImageNet validation set, utilizing clustering-related metrics such as NMI and ARI. 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 | Unsupervised image classification | | Dataset (including any stated split) | ImageNet 200 randomly selected classes (val) | | Metric | Top-1 Acc | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 3 of 3 | | 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 - [Top-1 Acc](): Higher is better; unit: PERCENT. - [Top-5 Acc](): Higher is better; unit: PERCENT. - [NMI](): Higher is better; unit: PERCENT. - [ARI](): Higher is better; unit: PERCENT. ## Recorded results | Method | Top-1 Acc | Result date | Report paper | | --- | --- | --- | --- | | SCAN | 58.1 | Not recorded | 68fa67d21e209131cea18ae5 | | SCAN | 56.3 | Not recorded | 68fa67d21e209131cea18ae5 | | K-means | 52.5 | Not recorded | 68fa67d21e209131cea18ae5 | ### SCAN Top-1 Acc: 58.1.
