# Action Recognition on K400 open-vocabulary Source: [Action Recognition on K400 open-vocabulary]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:37:38.145Z Evaluation of Action Recognition performance on the Kinetics-400 dataset under an open-vocabulary setting, utilizing Base, Novel, and Harmonic Mean metrics. 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) | K400 open-vocabulary | | Metric | Base Accuracy | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 5 of 5 | | 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 - [Base Accuracy](): Higher is better; unit: PERCENT. - [Novel Accuracy](): Higher is better; unit: PERCENT. - [Harmonic Mean Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | Base Accuracy | Result date | Report paper | | --- | --- | --- | --- | | FROSTER | 78.8 | Not recorded | 692d2153d6b0dd33429319bc | | FROSTER | 78.3 | Not recorded | 692d2153d6b0dd33429319bc | | FROSTER | 77.8 | Not recorded | 692d2153d6b0dd33429319bc | | Open-VCLIP | 76.5 | Not recorded | 692d2153d6b0dd33429319bc | | ViFi-CLIP | 76.4 | Not recorded | 692d2153d6b0dd33429319bc | ### FROSTER Base Accuracy: 78.8.
