Hierarchical Context-aware Network for Dense Video Event Captioning (2021.acl-long)
Copied to clipboard
| Challenge: | Existing technologies for dense video event captioning generate fine-grained captions for all events in a long untrimmed video. |
| Approach: | They propose a hierarchical context-aware network for dense video event captioning to capture context from various aspects. |
| Outcome: | The proposed model outperforms the existing model on youcook2 and activitynet . it generates coherent captions for events in a long untrimmed video . |
Scattered Hypothesis Generation for Open-Ended Event Forecasting (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for event forecasting focus on the most probable outcomes, neglecting the intrinsic uncertainty of real-world events. |
| Approach: | They propose a reinforcement learning framework that optimizes inclusiveness and diversity of the hypothesis by integrating validity-gated score into the overall objective. |
| Outcome: | The proposed framework outperforms baselines on two real-world benchmark datasets. |
