In general, geometries of Petrov type II do not admit symmetries in terms of Killing vectors or spinors.

Action anticipation is critical in scenarios where one needs to react before the action is finalized.
In contrast to the widely studied problem of recognizing an action given a complete sequence, action anticipation aims to identify the action from only partially available videos.
We outperform the state-of-the-art methods that, as us, rely only on RGB frames as input for both action recognition and anticipation.
