EgoAdapt: Adaptive Multisensory Distillation and Policy Learning for Efficient Egocentric Perception

Modern perception models, particularly those designedfor multisensory egocentric tasks, have achieved remark-able performance but often come with substantial compu-tational costs. These high demands pose challenges forreal-world deployment, especially in resource-constrainedenvironments. In this paper, we introduce EGOADAPT, aframework that adaptively performs cross-modal distilla-tion and policy learning to enable efficient inference acrossdifferent egocentric perception tasks, including egocentricaction recognition, active speaker localization, and behav-ior anticipation. Our proposed policy module is adapt-able to task-specific action spaces, making it broadly appli-cable. Experimental results on three challenging egocen-tric datasets—EPIC-Kitchens, EasyCom, and Aria Every-day Activities—demonstrate that our method significantlyenhances efficiency, reducing GMACs by up to 89.09%, pa-rameters up to 82.02%, and energy up to 9.6×, while stillon-par and in many cases outperforming, the performanceof corresponding state-of-the-art models.
