Abstract

Complex human activities involve many sub-activities that have further sub-activities and so on.  Understanding the sequence of these steps iscritical to understanding long-term complex activities, like those involved incooking, healthcare, interaction, etc.  However, manually annotating these sub-activities is cumbersome and error-prone.  We hence propose a deep learning model that takes a first step toward understanding such complex human activities.  Our first model on this hard problem seeks to automatically discover the temporal segments in each video.  We apply this model to instructional cooking videos that are unstructured, untrimmed and fromthe web.

We experiment with a new version of our YouCook dataset that containstwenty-five samples of more than 100 different cooking recipes, fully annotated with natural language recipes.  Time permitting, I will discuss the incorporation of language models both in guidance for the process learning and for the description of the steps.  I will also discuss related work that incorporates human-input as side information during inference on the problem of pose estimation.
