Researchers have introduced PKS$^4$, a novel approach to efficient video understanding that addresses the computational challenges of long video sequences. This method integrates a plug-and-play module with linear-complexity temporal scanning, bypassing the need for computationally expensive attention mechanisms and multi-layer adapters. PKS$^4$ extracts kinematic priors to guide State Space Models, enabling adaptive state tracking and significantly reducing training compute by approximately 10x compared to existing video SSMs while achieving state-of-the-art results on action recognition benchmarks.
