Abstract
\nSystems that support expre ssive\, situated natural language interactions are essential for expanding access to complex computing systems\, such as robots and databases\, to n on-experts. Reasoning and learning in such natural language interactions i s a challenging open problem. For example\, resolving sentence meaning req uires reasoning not only about word meaning\, but also about the interacti on context\, including the history of the interaction and the situated env ironment. In addition\, the sequential dynamics that arise between user an d system in and across interactions make learning from static data\, i.e.\ , supervised data\, both challenging and ineffective. However\, these same interaction dynamics result in ample opportunities for learning from impl icit and explicit feedback that arises naturally in the interaction. This lays the foundation for systems that continually learn\, improve\, and ada pt their language use through interaction\, without additional annotation effort. In this talk\, I will focus on these challenges and opportunities. First\, I will describe our work on modeling dependencies between languag e meaning and interaction context when mapping natural language in interac tion to executable code. In the second part of the talk\, I will describe our work on language understanding and generation in collaborative interac tions\, focusing on continual learning from explicit and implicit user fee dback.

\nModern learning architectures for natural language processing have been very suc cessful in incorporating a huge amount of texts into their parameters. How ever\, by and large\, such models store and use knowledge in distributed a nd decentralized ways. This proves unreliable and makes the models ill-sui ted for knowledge-intensive tasks that require reasoning over factual info rmation in linguistic expressions. In this talk\, I will give a few examp les of exploring alternative architectures to tackle those challenges. In particular\, we can improve the performance of such (language) models by r epresenting\, storing and accessing knowledge in a dedicated memory compon ent.
\nThis talk is based on several joint works with Yury Zemlyanskiy (Google Research)\, Michiel de Jong (USC and Google Research)\, William Cohen (Google Research and CMU) and our other collabo rators in Google Research.
