The competition task was to build a network intrusion detector, a predictive model capable of distinguishing between ``bad'' connections, called intrusions or attacks, and ``good'' normal connections. This database contains a standard set of data to be audited, which includes a wide variety of intrusions simulated in a military network environment.","description_withheld":null,"homepage":"https://archive.ics.uci.edu/ml/datasets/kdd+cup+1999+data","introduced_date":"1999-01-01","introduced_date_note":null,"introduced_by":null,"license":null,"modalities":[],"tasks":[{"name":"Anomaly Detection","url":"/task/anomaly-detection","datasets_with_task":"/datasets/task/anomaly-detection"}],"languages":[],"variants":["KDD Cup 1999"],"data_loaders":[{"repo":"https://github.com/tensorflow/datasets","url":"https://www.tensorflow.org/datasets/catalog/kddcup99","frameworks":["tf","pytorch","jax"]}],"num_papers_in_archive":5,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/anomaly-detection-on-kdd-cup-1999","task":"Anomaly Detection","dataset_variant":"KDD Cup 1999","rows":1,"metrics":["F1-Score"],"first_row_in_archive_order":{"model":"RCALAD","paper":"/paper/regularized-complete-cycle-consistent-gan-for","metrics":{"F1-Score":"95.4"},"code_links":[{"title":"zahradehghanian97/rcalad","url":"https://github.com/zahradehghanian97/rcalad"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/regularized-complete-cycle-consistent-gan-for","title":"Spot The Odd One Out: Regularized Complete Cycle Consistent Anomaly Detector GAN","date":"2023-04-16","rows_on_this_dataset":1,"code_links":1,"syntology":null}],"syntology_totals":{"read_at":"2026-09-25T09:33:49+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."}
