Open Set Action Recognition

Open Set Action Recognition is a crucial task in the field of computer vision, aiming to recognize unknown actions beyond predefined categories. This task not only focuses on accurately identifying the pre-defined action classes but also strives to detect and handle unseen actions, thereby enhancing the system's generalization and robustness. Its application value lies in adapting to ever-changing real-world scenarios, providing more comprehensive support for intelligent surveillance, human-computer interaction, and behavior analysis.
