  • NL Seminar-Conversational Question Answering

    Thu, Oct 25, 2018 @ 11:00 AM - 12:00 PM

    Information Sciences Institute

    Conferences, Lectures, & Seminars


    Speaker: Scott Yih, AI2

    Talk Title: Conversational Question Answering

    Series: Natural Language Seminar

    Abstract: Humans seek information in a conversational manner, by asking follow-up questions for additional information based on what they have already learned. In this talk, I will first introduce the task of sequential question answering 1. which aims to fulfill user's information need by answering a series of simple, but interdependent questions regarding a given table. Treating this task as a semantic parsing problem, we developed a policy shaping mechanism that incorporates prior knowledge and an update equation that generalizes three different families of learning algorithms 2. After that, I will then talk briefly about QuAC, a new dataset for Question Answering in Context. QuAC targets the scenario where the information source is unstructured text 3. and thus can be viewed as a conversational machine comprehension task. New, unpublished model ideas will also be discussed.

    Biography: Scott Wen-tau Yih is a Principal Research Scientist at Allen Institute for Artificial Intelligence AI2. His research interests include natural language processing, machine learning and information retrieval. Yih received his Ph.D. in computer science at the University of Illinois at Urbana-Champaign. His work on joint inference using integer linear programming ILP has been widely adopted in the NLP community for numerous structured prediction problems. Prior to joining AI2, Yih has spent 12 years at Microsoft Research, working on a variety of projects including email spam filtering, keyword extraction and search & ad relevance. His recent work focuses on continuous representations and neural network models, with applications in knowledge base embedding, semantic parsing and question answering. Yih received the best paper award from CoNLL-2011, an outstanding paper award from ACL-2015 and has served as area co-chairs HLT-NAACL-12, ACL-14, EMNLP-16,17,18, program co-chairs CEAS-09, CoNLL-14 and action associated editors TACL, JAIR in recent years. He is also a co-presenter for several tutorials on topics including Semantic Role Labeling NAACL-HLT-06, AAAI-07, Deep Learning for NLP SLT-14, NAACL-HLT-15, IJCAI-16, NLP for Precision Medicine ACL-17, AAAI-18.

  • Sender Decomposition of Cache-Aided Communications and Distributed Computing

    Thu, Oct 25, 2018 @ 01:00 PM - 02:00 PM

    Ming Hsieh Department of Electrical Engineering

    Conferences, Lectures, & Seminars


    Speaker: Petros Elia, Communication Systems Department, EURECOM, Sophia Antipolis, France

    Talk Title: Sender Decomposition of Cache-Aided Communications and Distributed Computing

    Series: Center for Cyber-Physical Systems and Internet of Things

    Abstract: Recent results have shown that the data-redundancy that can exist in cache-aided communication networks as well as in (coded) distributed computing, can allow for substantial reductions in communication delays. These approaches though face various fundamental challenges that severely reduce the theoretically unbounded gains to much smaller gains. The work here shows a simple way without any additional data exchange between the communicating/computing nodes to decompose the problems of coded caching and coded distributed computing, into problems of smaller dimensionality with much better overall performance. Different manifestations of this "decomposition" phenomenon are explored, each revealing interesting boosts in performance and a direct amelioration of different bottlenecks like the "uneven category bottleneck", the "straggler bottleneck" and the "finite data-set bottleneck".


    Biography: Petros Elia received the B.Sc. degree from the Illinois Institute of Technology, and the M.Sc. and Ph.D. degrees in electrical engineering from the University of Southern California in 2001 and 2006 respectively. He is a professor with the Department of Communication Systems at EURECOM, in Sophia Antipolis, France. His latest research deals with information-theoretic aspects of caching, as well with different problems in the area of complexity-constrained communications, coding theory, and surveillance networks. He is a Fulbright scholar, the co-recipient of the NEWCOM++ distinguished achievement award 2008-2011 for a sequence of publications on the topic of complexity in wireless communications, and the recipient of the ERC Consolidator Grant 2017-2022 on cache-aided wireless communications.
