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.
\nBiography
\nAlane Suhr is a PhD Cand idate in the Department of Computer Science at Cornell University\, advis ed by Yoav Artzi. Her research spans natural language processing\, machine learning\, and computer vision\, with a focus on building systems that pa rticipate and continually learn in situated natural language interactions with human users. Alane’s work has been recognized by paper awards at ACL and NAACL\, and has been supported by fellowships and grants\, including a n NSF Graduate Research Fellowship\, a Facebook PhD Fellowship\, and resea rch awards from AI2\, ParlAI\, and AWS. Alane has also co-organized multip le workshops and tutorials appearing at NeurIPS\, EMNLP\, NAACL\, and ACL. Previously\, Alane received a BS in Computer Science and Engineering as a n Eminence Fellow at the Ohio State University.

\nI will present our work on data augmentation using style transfer as a way to im prove domain adaptation in sequence labeling tasks. The target domain is s ocial media data\, and the task is named entity recognition (NER). The pre mise is that we can transform the labelled out of domain data into somethi ng that stylistically is more closely related to the target data. Then we can train a model on a combination of the generated data and the smaller a mount of in domain data to improve NER prediction performance. I will show recent empirical results on these efforts.
\nIf time allows\, I will also give an overview of other research projects I’m currently leading at RiTUAL (Research in Text Understanding and Analysis of Language) lab. The common thread among all these research problems is t he scarcity of labeled data.
