Action detection plays an important role in high-level video understanding and media interpretation.

... However, they often universally treat all the actors without considering the consistency and distinctness between individuals

... we explicitly highlight the identity information of the actors in terms of both long-term and short-term context through a graph memory network

... develop a dual attention module (DAM) to generate identity-aware constraint to reduce the influence of interference by the actors of different identities.

... demonstrate the effectiveness of our method, which achieves state-of-the-art results on AVA v2.1 and v2.2.
