A Baseline Study and Benchmark for Few-Shot Open-Set Action Recognition with Feature Residual Discrimination
Researchers have introduced a new method for few-shot open-set action recognition in videos, addressing the limitations of existing closed-set assumptions. Their proposed Feature-Residual Discriminator (FR-Disc) architecture adapts previous skeletal data techniques to the more complex video domain. Experiments across five datasets show that FR-Disc significantly improves the ability to reject unknown actions without negatively impacting accuracy on known actions, establishing a new state-of-the-art for this task.
