It leverages the training data from existing datasets ([LVIS](/dataset/lvis), [OpenImages](/dataset/openimages-v6) and [Object365](/dataset/objects365)) with carefully designed principles, and curate a larger dataset for improved detector pre-training. BigDetection dataset has 600 object categories and contains 3.4M training images with 36M object bounding boxes.","description_withheld":null,"homepage":"https://github.com/amazon-research/bigdetection","introduced_date":"2022-03-24","introduced_date_note":null,"introduced_by":{"paper":"/paper/bigdetection-a-large-scale-benchmark-for","title":"BigDetection: A Large-scale Benchmark for Improved Object Detector Pre-training","first_author":"Likun Cai","url":null},"license":{"name":"Custom","url":"https://github.com/amazon-research/bigdetection#license"},"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"Object Detection","url":"/task/object-detection","datasets_with_task":"/datasets/task/object-detection"}],"languages":[],"variants":["BigDetection","BigDetection val"],"data_loaders":[{"repo":"https://github.com/amazon-research/bigdetection","url":"https://github.com/amazon-research/bigdetection","frameworks":[]}],"num_papers_in_archive":7,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/object-detection-on-bigdetection-val","task":"Object Detection","dataset_variant":"BigDetection val","rows":6,"metrics":["AP","AP50","AP75"],"first_row_in_archive_order":{"model":"Cascade R-CNN (R50-FPN)","paper":"/paper/bigdetection-a-large-scale-benchmark-for","metrics":{"AP":"24.1","AP50":"33.0","AP75":"25.8"},"code_links":[{"title":"amazon-science/bigdetection","url":"https://github.com/amazon-science/bigdetection"},{"title":"amazon-research/bigdetection","url":"https://github.com/amazon-research/bigdetection"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/bigdetection-a-large-scale-benchmark-for","title":"BigDetection: A Large-scale Benchmark for Improved Object Detector Pre-training","date":"2022-03-24","rows_on_this_dataset":6,"code_links":2,"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."}
