Open Set Action Recognition

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.

Most implemented papers archive 2025-07-28

5 shown of 5 papers with code (8 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.

• InternVideo: General Video Foundation Models via Generative and Discriminative Learning
  6 Dec 2022 2 repositories listed Syntology ran 3 of 3 samples · 0 unverified
  Specifically, InternVideo efficiently explores masked video modeling and video-language contrastive learning as the pretraining objectives, and selectively coordinates video representations of these two complementary…
• Evidential Deep Learning for Open Set Action Recognition
  21 Jul 2021 2 repositories listed Syntology ran 5 of 5 samples · 0 unverified · 4 pointer-only (licence)
  Different from image data, video actions are more challenging to be recognized in an open-set setting due to the uncertain temporal dynamics and static bias of human actions.
• Navigating Open Set Scenarios for Skeleton-based Action Recognition
  11 Dec 2023 1 repository listed Syntology ran 8 of 12 samples · 4 unverified · 12 pointer-only (licence)
  In real-world scenarios, human actions often fall outside the distribution of training data, making it crucial for models to recognize known actions and reject unknown ones.
• SOAR: Scene-debiasing Open-set Action Recognition
  3 Sep 2023 1 repository listed Syntology ran 8 of 12 samples · 4 unverified
  The former prevents the decoder from reconstructing the video background given video features, and thus helps reduce the background information in feature learning.
• Enlarging Instance-specific and Class-specific Information for Open-set Action Recognition
  25 Mar 2023 1 repository listed Syntology ran 1 of 1 samples · 0 unverified · 1 pointer-only (licence)
  In this paper, we begin with analyzing the feature representation behavior in the open-set action recognition (OSAR) problem based on the information bottleneck (IB) theory, and propose to enlarge the instance-specific…

Syntology lines on 5 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.
