Center node: "joint visual temporal embedding for unsupervised learning of actions in untrimmed sequences"
  Abstract: Understanding the structure of complex activities in videos is one of the many challenges faced by action recognition methods. To overcome this challenge, not only do methods need a solid knowledge of the visual structure of underlying features but also a good interpretation of how they could change over time. Consequently, action segmentation tasks must take into account not only the visual cues from individual frames, but their characteristics as a temporal sequence of features. #R##N#This work presents our findings on the impact of incorporating both visual and temporal learning on an unsupervised action segmentation pipeline. We introduce a novel approach to extract relevant visual and temporal features from untrimmed sequences for the temporal localization of sub-activities within complex actions without any labeling information. Through extensive experimentation on two benchmark datasets -- Breakfast Actions, and YouTube Instructions -- we show that the proposed approach is able to provide a meaningful visual and temporal embedding from the visual cues from contiguous video frames and that it indeed helps in temporal segmentation.
