ATW CNN architecture. Three CNN streams are used to process spatial RGB images, temporal optical flow images, and temporal warped optical flow images, respectively. An attention model is employed to assign temporal weights between snippets for each stream/modality. Weighted sum is used to fuse predictions from the three streams/modalities.
