MLP-AIR: An effective MLP-based module for actor interaction relation learning in group activity recognition

Guoliang Xu, Jianqin Yin, Shaojie Zhang, Moonjun Gong

Abstract: Highlights•We propose an MLP-based module for interaction relation modeling implicitly.•Our module is designed by MLP entirely, simplifying the module’s structure.•Our module is a universal module that can be used for other methods.
