# Action Recognition on LT-NTU IF = 100 120 (cross-subject) Source: [Action Recognition on LT-NTU IF = 100 120 (cross-subject)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:54:38.611Z Evaluation of video action recognition performance on the LT-NTU IF=100 120 dataset using the cross-subject protocol, reporting Top-1 Accuracy broken down by action frequency (Many, Medium, Few). 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) | LT-NTU IF = 100 120 (cross-subject) | | Metric | Overall Top-1 Acc | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 17 of 17 | | 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 - [Overall Top-1 Acc](): Higher is better; unit: PERCENT. - [Top-1 Acc (Many)](): Higher is better; unit: PERCENT. - [Top-1 Acc (Medium)](): Higher is better; unit: PERCENT. - [Top-1 Acc (Few)](): Higher is better; unit: PERCENT. ## Recorded results | Method | Overall Top-1 Acc | Result date | Report paper | | --- | --- | --- | --- | | Shap-Mix | 73 | Not recorded | 68fa74231e209131cea5fe66 | | GLMC | 71.5 | Not recorded | 68fa74231e209131cea5fe66 | | BS+Max Norm | 70.3 | Not recorded | 68fa74231e209131cea5fe66 | | Balanced Softmax (BS) | 69.6 | Not recorded | 68fa74231e209131cea5fe66 | | Focal Loss | 69.4 | Not recorded | 68fa74231e209131cea5fe66 | | Remix-DRW | 69.3 | Not recorded | 68fa74231e209131cea5fe66 | | PaCo | 67.9 | Not recorded | 68fa74231e209131cea5fe66 | | IB Loss | 67.8 | Not recorded | 68fa74231e209131cea5fe66 | | Mixup | 66.9 | Not recorded | 68fa74231e209131cea5fe66 | | BCL | 66.9 | Not recorded | 68fa74231e209131cea5fe66 | | LDAM-DRW | 66.8 | Not recorded | 68fa74231e209131cea5fe66 | | FSA | 66.7 | Not recorded | 68fa74231e209131cea5fe66 | | BRL | 66.3 | Not recorded | 68fa74231e209131cea5fe66 | | RIDE (3 experts) | 65.2 | Not recorded | 68fa74231e209131cea5fe66 | | Cross-Entropy Loss | 64.2 | Not recorded | 68fa74231e209131cea5fe66 | | CB Loss | 63.2 | Not recorded | 68fa74231e209131cea5fe66 | | ROS | 61 | Not recorded | 68fa74231e209131cea5fe66 | ### Shap-Mix Overall Top-1 Acc: 73.
