Abstract

Human actions often involve complex interactions across several inter-related objects in the scene. However, existing approaches to fine-grained video understanding or visual relationship detection often rely on single object representation or pairwise object relationships.

In this paper, we propose to efficiently learn higher-order interactions between arbitrary subgroups of objects for fine-grained video understanding. We demonstrate the impact of modeling object interactions towards significantly improving accuracy for both action recognition and video captioning.

To the best of our knowledge, this is the first work modeling object interactions on open domain large-scale video datasets.
