{"url":"/dataset/skab","name":"SKAB","full_name":"Skoltech Anomaly Benchmark","description_markdown":"SKAB is designed for evaluating algorithms for anomaly detection. The benchmark currently includes 30+ datasets plus Python modules for algorithms’ evaluation. Each dataset represents a multivariate time series collected from the sensors installed on the testbed. All instances are labeled for evaluating the results of solving outlier detection and changepoint detection problems.","description_withheld":null,"homepage":"https://github.com/waico/SKAB","introduced_date":"2020-11-28","introduced_date_note":null,"introduced_by":null,"license":{"name":"GNU General Public License v3.0","url":"https://github.com/waico/SKAB/blob/master/LICENSE"},"modalities":[{"name":"Time series","url":"/datasets/modality/time-series"},{"name":"Tables","url":"/datasets/modality/tables"}],"tasks":[{"name":"Anomaly Detection","url":"/task/anomaly-detection","datasets_with_task":"/datasets/task/anomaly-detection"},{"name":"Outlier Detection","url":"/task/outlier-detection","datasets_with_task":"/datasets/task/outlier-detection"},{"name":"Change Point Detection","url":"/task/change-point-detection","datasets_with_task":"/datasets/task/change-point-detection"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["SKAB"],"data_loaders":[{"repo":"https://github.com/waico/SKAB","url":"https://github.com/waico/SKAB","frameworks":[]}],"num_papers_in_archive":3,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/change-point-detection-on-skab","task":"Change Point Detection","dataset_variant":"SKAB","rows":7,"metrics":["NAB (standard)","NAB (lowFP)","NAB (LowFN)"],"first_row_in_archive_order":{"model":"LSTMCaps","paper":"/paper/hybridization-of-capsule-and-lstm-networks","metrics":{"NAB (LowFN)":"31.59","NAB (lowFP)":"17.14","NAB (standard)":"27.77"},"code_links":[]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"},{"leaderboard":"/sota/outlier-detection-on-skab","task":"Outlier Detection","dataset_variant":"SKAB","rows":1,"metrics":["Average F1"],"first_row_in_archive_order":{"model":"LSTMCaps","paper":"/paper/hybridization-of-capsule-and-lstm-networks","metrics":{"Average F1":"0.74"},"code_links":[]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/hybridization-of-capsule-and-lstm-networks","title":"Hybridization of Capsule and LSTM Networks for unsupervised anomaly detection on multivariate data","date":"2022-02-11","rows_on_this_dataset":2,"code_links":0,"syntology":null},{"paper":"/paper/unsupervised-offline-changepoint-detection","title":"Unsupervised Offline Changepoint Detection Ensembles","date":"2021-05-09","rows_on_this_dataset":6,"code_links":1,"syntology":null}],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
