HPNet: Dynamic Trajectory Forecasting with Historical Prediction Attention

CVPR 2024poster

Predicting the trajectories of road agents is essential for autonomous driving systems. The recent mainstream methods follow a static paradigm which predicts the future trajectory by using a fixed duration of historical frames. These methods make the predictions independently even at adjacent time s…

Texts as Images in Prompt Tuning for Multi-Label Image Recognition

CVPR 2023poster

Prompt tuning has been employed as an efficient way to adapt large vision-language pre-trained models (e.g. CLIP) to various downstream tasks in data-limited or label-limited settings. Nonetheless, visual data (e.g., images) is by default prerequisite for learning prompts in existing methods. In thi…
