Talk Title: THE LIMITS OF UNSUPERVISED SYNTAX AND THE IMPORTANCE OF GROUNDING IN LANGUAGE ACQUISITION
Series: Natural Language Seminar
Abstract: The future of self driving cars, personal robots, smart homes, and intelligent assistants hinges on our ability to communicate with computers. The failures and miscommunications of Siri style systems are untenable and become more problematic as machines become more pervasive and are given more control over our lives. Despite the creation of massive proprietary datasets to train dialogue systems, these systems still fail at the most basic tasks. Further, their reliance on big data is problematic. First, successes in English cannot be replicated in most of the six thousand plus languages of the world. Second, while big data has been a boon for supervised training methods, many of the most interesting tasks will never have enough labeled data to actually achieve our goals. It is, therefore, important that we build systems which can learn from naturally occurring data and grounded, situated interactions.
In this talk I will discuss work from my thesis on the unsupervised acquisition of syntax which harnesses unlabeled text in over a dozen languages. This exploration leads us to novel insights into the limits of semantics free language learning. Having isolated these stumbling blocks I will then present my recent work on language grounding where we attempt to learn the meaning of several linguistic constructions via interaction with the world.
Biography: Yonatan Bisk has research that focuses on Natural Language Processing from naturally occurring data unsupervised and weakly supervised data. He is a postdoc researcher with Daniel Marcu at USCs Information Sciences Institute. Previously, he received his PhD from the University of Illinois at Urbana Champaign under Julia Hockenmaier and his BS from the University of Texas at Austin.
