Computer Vision

Weakly-supervised Video Anomaly Detection (WS-VAD) refers to identifying unusual or anomalous behaviors within video sequences using models trained primarily on video-level labels, without explicit frame-level annotations. Unlike fully-supervised methods, weakly-supervised approaches significantly reduce annotation costs by leveraging coarse labels (e.g., videos labeled as normal or anomalous). The primary challenge of this task is accurately localizing temporal anomalies and effectively distinguishing subtle anomalous activities from normal background events, relying only on limited supervision signals.

Benchmarks archive 2025-07-28

2 leaderboard tables shown for this task, 2 with rows (a “benchmark” on this site is a table with at least one row, as on /sota), ordered by row count. “Best model” is the first row in the archive's own order at snapshot; nothing is re-ranked here and metric direction is not recorded in the archive. PwC's Trend sparklines are not in the archive, so that column is omitted.

Syntology column: samples harvested from the paper's repositories and executed on synthesized fixtures; “ran” is not a correctness claim and does not order the table. A dash means no Syntology record for that paper, not a recorded non-run. Read from the graph 2026-09-24.

Libraries

Not in the archive: the export carries no per-task library table, so there is nothing to show at snapshot 2025-07-28.

21 shown of 21 papers with code (36 tagged with this task in all), ordered by repositories listed in the archive, not by stars (the archive holds no stars, so PwC's “Social” and “Latest” sorts cannot be reproduced). Papers without a page here are shown as plain text.

Syntology lines on 11 of the papers shown; no Syntology record for the others (a paper without an arXiv id cannot be joined to the graph, and absence from the graph layer is not a recorded non-run). “Ran” means the sample executed on a synthesized fixture, not that the paper's result was reproduced.
