Speaker: Jie Xu, Assistant Professor at University of Miami
Talk Title: Real time knowledge discovery and decision making
Series: AI Seminar
Abstract: As the world becomes ever more connected and instrumented, decision makers have ever more rapid access to ever changing and growing streams of data, but this makes the decision makers problems ever more complex as well, because it is impossible to learn everything in the time frame in which decisions must be made. What the decision maker must do, therefore, is to discover in real time what is relevant in the enormous stream of data and use the relevant information to make good decisions. This talk presents a systematic framework and associated algorithms that enable a decision maker to do this, and shows how to use them in real time traffic prediction as an application scenario. One key challenge in traffic prediction is how much to rely on prediction models that are constructed using historical data in real time traffic situations. Our decision framework learns from the current traffic situation in real time and predicts the future traffic by matching the current situation to the most effective prediction model. The algorithms we propose yield strong performance guarantees for both the long run and the short run. The applications are numerous besides traffic prediction, including patient monitoring, surveillance, social networks etc.
Biography: Jie Xu is an Assistant Professor in the Department of Electrical and Computer Engineering at the University of Miami. His research mainly focuses on game theory and learning theory. His interests lie in both developing the theory in these areas and applying it in real world engineering systems, including communication networks, cyber-security systems, online social platforms and healthcare informatics. Jie received his BS and MS degrees in Electronic Engineering from Tsinghua University in China in 2008 and 2010, respectively, and a PhD degree in Electrical Engineering from University of California, Los Angeles (UCLA) in 2015. In 2014, he was with IBM T. J. Watson Research Center where he interned in the Clinical Stream Analytics team during the summer. Jie is a recipient of Distinguished PhD Dissertation Award at UCLA.

NL Seminar-Interactive scene design using natural language

Speaker: Angel Chang , (Stanford University)
Talk Title: Interactive scene design using natural language
Series: Natural Language Seminar
Abstract: Designing 3D scenes is currently a creative task that requires significant expertise and effort in using complex 3D design interfaces. This design process starts in contrast to the easiness with which people can use language to describe real and imaginary environments. We present an interactive text to 3D scene generation system that allows a user to design 3D scenes using natural language. A user provides input text from which we extract explicit constraints on the objects that should appear in the scene. Given these explicit constraints, the system then uses a spatial knowledge base learned from an existing database of 3D scenes and 3D object models to infer an arrangement of the objects forming a natural scene matching the input description. Using textual commands the user can then iteratively refine the created scene by adding, removing, replacing, and manipulating objects.
Biography: Angel Chang recently received her PhD after working in the Stanford NLP group where she was advised by Chris Manning. Her research focuses on the intersection of natural language understanding, computer graphics, and AI. She is currently a visiting expert at Tableau Research.
