# Action Recognition on HMDB-51 (Top-1 Accuracy) Source: [Action Recognition on HMDB-51 (Top-1 Accuracy)]() Collection index: [llms.txt]() Data updated: 2026-05-25T08:19:05.867Z Evaluation of video action recognition performance on the HMDB-51 dataset, reporting standard Top-1 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) | HMDB-51 | | Metric | Top-1 Accuracy | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 36 of 36 | | 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 - [Top-1 Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | Top-1 Accuracy | Result date | Report paper | | --- | --- | --- | --- | | SimVA | 70.1 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | TC-CLIP | 68.8 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | OST | 68.2 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | BDC-CLIP | 67.5 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | SimVA | 67.5 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ViFi-CLIP | 66.8 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | TC-CLIP | 65.5 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | BDC-CLIP | 65.3 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | OST | 64.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ViFi-CLIP | 64.5 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | X-CLIP | 64 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | SimVA | 64 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | TC-CLIP | 63.3 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | BDC-CLIP | 63.1 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | OST | 62.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | X-CLIP | 62.8 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ViFi-CLIP | 62.7 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | A5 | 62.4 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | SimVA | 60.7 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | BDC-CLIP | 59.2 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ActionCLIP | 59.1 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | OST | 59.1 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | TC-CLIP | 58.6 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ActionCLIP | 57.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ActionCLIP | 57.3 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | X-CLIP | 57.3 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ViFi-CLIP | 57.2 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | A5 | 56 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | X-CLIP | 53 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | A5 | 50.7 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | ActionCLIP | 47.5 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | CLIP | 41.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | CLIP | 41.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | CLIP | 41.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | CLIP | 41.9 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | | A5 | 39.7 | Not recorded | 6a13d7586f71c5ae7dc9e6cb | ### SimVA Top-1 Accuracy: 70.1.
