# Action Recognition on THUMOS 14 (test) Source: [Action Recognition on THUMOS 14 (test)]() Collection index: [llms.txt]() Data updated: 2026-02-27T06:10:37.317Z Evaluation of video Action Recognition performance on the test split of the THUMOS 14 dataset, typically measured using Accuracy. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Action Recognition | | Dataset (including any stated split) | THUMOS 14 (test) | | Metric | mAP | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 39 of 39 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [mAP](): Higher is better; unit: PERCENT. - [Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | mAP | Result date | Report paper | | --- | --- | --- | --- | | R(2+1)D & DSN (M = 1) | 84.7 | Not recorded | 68fa68381e209131cea1ae07 | | R(2+1)D & DSN (M = 1) | 83.1 | Not recorded | 68fa68381e209131cea1ae07 | | R(2+1)D | 82.6 | Not recorded | 68fa68381e209131cea1ae07 | | UntrimmedNet (soft) | 82.2 | Not recorded | 68fa68381e209131cea1ae07 | | R(2+1)D | 81.9 | Not recorded | 68fa68381e209131cea1ae07 | | UntrimmedNet (hard) | 81.2 | Not recorded | 68fa68381e209131cea1ae07 | | TSN | 80.1 | Not recorded | 68fa68381e209131cea1ae07 | | R(2+1)D & DSN (M = 1) | 78.4 | Not recorded | 68fa68381e209131cea1ae07 | | R3D-RGB & DSN (M = 6) | 75.2 | Not recorded | 68fa68381e209131cea1ae07 | | R3D-RGB & TSN (6 seg) | 73.6 | Not recorded | 68fa68381e209131cea1ae07 | | R(2+1)D | 73.5 | Not recorded | 68fa68381e209131cea1ae07 | | Objects+Motion | 71.6 | Not recorded | 68fa68381e209131cea1ae07 | | Jain et al. | 71 | Not recorded | 68fa68381e209131cea1ae07 | | Two Stream | 66.1 | Not recorded | 68fa68381e209131cea1ae07 | | Motion | 63.1 | Not recorded | 68fa68381e209131cea1ae07 | | ELM | 62.3 | Not recorded | 68fa68381e209131cea1ae07 | | iDT+CNN | 62 | Not recorded | 68fa68381e209131cea1ae07 | | RGB+EMV | 61.5 | Not recorded | 68fa68381e209131cea1ae07 | | CDC | 44.4 | Not recorded | 68fa63661e209131ce9fe6be | | Conv & De-conv | 41.7 | Not recorded | 68fa63661e209131ce9fe6be | | MultiLSTM | 41.3 | Not recorded | 68fa63661e209131ce9fe6be | | LSTM | 39.3 | Not recorded | 68fa63661e209131ce9fe6be | | CDC | 37.4 | Not recorded | 68fa63661e209131ce9fe6be | | C3D + LinearInterp | 37 | Not recorded | 68fa63661e209131ce9fe6be | | Two-stream CNN | 36.2 | Not recorded | 68fa63661e209131ce9fe6be | | Single-frame CNN | 34.7 | Not recorded | 68fa63661e209131ce9fe6be | ### R(2+1)D & DSN (M = 1) mAP: 84.7.
