This research deals with the task of video classification, with a particular focus on action recognition, which is essential for a comprehensive understanding of videos. In the typical scenario, there is a list of semantic categories to be modeled, and example clips are given together with their associated category label, indicating which action of interests happens in that clip. No information is given about where or when the action happens, or why the annotator considered the clip to belong to a sometimes ambiguous category.Within the framework of the bag-of-words representation of videos, we explore how to leverage such weak labels from three points of view: (1) the use of coherent supervision from the earliest stages of the pipeline; (2...
