| Use CASA instead of LAV for frame retrieval | Penn Action · Penn Action frame retrieval | AP@15: 10.17% | Helped |
| Restrict context to embeddings up to the current frame rather than using the full sequence (ablation) | CASA · Penn Action sequence alignment | Phase classification: 92.20 -> 88.01 | Hurt |
| Restrict context to embeddings up to the current frame rather than using the full sequence (ablation) | CASA · Penn Action sequence alignment | Phase progress: 0.9449 -> 0.8454 | Hurt |
