  • AI Seminar- Uncovering meaning construction and representation in the reading brain

    Mon, Dec 15, 2014 @ 11:00 AM - 12:00 PM

    Information Sciences Institute

    Conferences, Lectures, & Seminars


    Speaker: Leila Wehbe , CMU

    Talk Title: Uncovering meaning construction and representation in the reading brain

    Series: Artificial Intelligence Seminar

    Abstract: How is information organized in the brain when it reads? Where and when do the required processes occur, such as perceiving the individual words, combining them with the previous words and maintaining a representation of the overall meaning?

    I will present results from a recent experiment in which we align context-based neural network language models and brain activity during reading. When processing a text word by word, both the brain and the neural networks perform the same processes. They both maintain a representation for the previous context. They both represent the properties of the incoming word and then integrate it with context. We study the alignment between the latent vectors used by these neural networks and the brain activity observed via Magnetoencephalography (MEG) when subjects read a chapter from Harry Potter and the Sorcerer’s Stone. For that purpose we apply the neural network to the same chapter the subjects are reading, and explore the ability of these vector representations to predict the observed word-by-word brain activity.

    Our novel results include a suggested time-line of how the brain updates its representation of context. They also demonstrate the incremental perception of every new word starting early in the visual cortex, moving next to the temporal lobes and finally to the frontal regions. Furthermore, the results suggest the integration process occurs in the temporal lobes after the new word has been perceived.

    This is joint work with Ashish Vaswani, Kevin Knight and Tom Mitchell, and is a part of a larger effort to understand how the brain organizes information in natural reading. I will describe this research direction. I will also mention results from a sister experiment in which we demonstrate how the brain areas involved in reading are processing different types of information (such as syntax, semantics or narrative information). This second experiment is joint work with Brian Murphy, Partha Talukdar, Alona Fyshe, Aaditya Ramdas and Tom Mitchell. Finally I will also mention some of our past and upcoming machine learning projects that aim to improve our methodological pipeline.

  • Zhisheng Niu Seminar

    Wed, Dec 17, 2014 @ 02:00 PM - 03:00 PM

    Ming Hsieh Department of Electrical Engineering

    Conferences, Lectures, & Seminars


    Speaker: Zhisheng Niu, Tsinghua University

    Talk Title: Characterizing Energy-Delay Tradeoff in Hyper-Cellular Networks with Base Station Sleeping Control

    Abstract: One of the key approaches to make the mobile communication networks more GREEN (Globally Resource-optimized and Energy-Efficient Networks) is to have the cellular architecture and radio resource allocation more adaptive to the environment and traffic variations, including making some lightly-loaded base stations (BSs) go to sleep. This is the concept of so-called TANGO (Traffic-Aware Network planning and Green Operation) and CHORUS (Collaborative and Harmonized Open Radio Ubiquitous Systems) published by the author earlier. To realize this, a new cellular framework, named hyper-cellular networks (HCN), has been proposed, in which the coverage of control signals is decoupled from the coverage of data signals so that the data coverage can be more elastic in accordance with the dynamics of traffic characteristics and QoS requirements. Due to this elasticity of HCN, some delay-insensitive users may have to experience some delay or other kind of QoS degradation when traffic load is high in order to save energy, i.e., energy can be traded off by some delay. The fundamental question then arises: how much energy can be traded off by a tolerable delay?

    Biography: Zhisheng Niu graduated from Northern Jiaotong University (currently Beijing Jiaotong University), Beijing, China, in 1985, and got his M.E. and D.E. degrees from Toyohashi University of Technology, Toyohashi, Japan, in 1989 and 1992, respectively. After spending two years at Fujitsu Laboratories Ltd., Kawasaki, Japan, he joined with Tsinghua University, Beijing, China, in 1994, where he is now a professor at the Department of Electronic Engineering, deputy dean of the School of Information Science and Technology, and director of Tsinghua-Hitachi Joint Lab on Environmental Harmonious ICT. He is also a guest chair professor of Shandong University. His major research interests include queueing theory, traffic engineering, mobile Internet, radio resource management of wireless networks, and green communication and networks.
    Dr. Niu has been an active volunteer for various academic societies, including Director for Conference Publications (2010-11) and Director for Asia-Pacific Board (2008-09) of IEEE Communication Society, Membership Development Coordinator (2009-10) of IEEE Region 10, Councilor of IEICE-Japan (2009-11), and council member of Chinese Institute of Electronics (2006-11). He is now a distinguished lecturer (2012-13) of IEEE Communication Society, editor of IEEE Wireless Communication Magazine, associate editor-in-chief of IEEE/CIC joint publication “China Communications”, standing committee member of both Communication Science and Technology Committee under the Ministry of Industry and Information Technology of China and Chinese Institute of Communications (CIC), and vice chair of the Information and Communication Network Committee of CIC.
    Dr. Niu received the Outstanding Young Researcher Award from Natural Science Foundation of China in 2009 and the Best Paper Awards (with his students) from the 13th, 15th and 19th Asia-Pacific Conference on Communication (APCC) in 2007, 2009, and 2013, respectively. He is now the Chief Scientist of the National Basic Research Program (so called “973 Project”) of China on "Fundamental Research on the Energy and Resource Optimized Hyper-Cellular Mobile Communication System" (2012-2016), which is the first national project on green communications in China. He is now a fellow of both IEEE and IEICE.

  • AI Seminar: Natural Language Semantics by Combining Logical and Distributional Methods using Probabilistic Logic

    Thu, Dec 18, 2014 @ 03:00 PM - 04:00 PM

    Information Sciences Institute

    Conferences, Lectures, & Seminars


    Speaker: Raymond Mooney, Professor at CS Dept, University of Texas at Austin

    Talk Title: Natural Language Semantics by Combining Logical and Distributional Methods using Probabilistic Logic

    Series: AISeminar

    Abstract: Traditional logical approaches to semantics and newer distributional or vector space approaches have complementary strengths and weaknesses.We have developed methods that integrate logical and distributional models by using a CCG-based parser to produce a detailed logical form for each sentence, and combining the result with soft inference rules derived from distributional semantics that connect the meanings of their component words and phrases. For recognizing textual entailment (RTE) we use Markov Logic Networks (MLNs) to combine these representations, and for Semantic Textual Similarity (STS) we use Probabilistic Soft Logic (PSL). We present experimental results on standard benchmark datasets for these problems and emphasize the advantages of combining logical structure of sentences with statistical knowledge mined from large corpora.

    Biography: Raymond J. Mooney is a Professor in the Department of Computer Science at the University of Texas at Austin. He received his Ph.D. in 1988 from the University of Illinois at Urbana/Champaign. He is an author of over 150 published research papers, primarily in the areas of machine learning and natural language processing. He was the President of the International Machine Learning Society from 2008-2011, program co-chair for AAAI 2006, general chair for HLT-EMNLP 2005, and co-chair for ICML 1990. He is a Fellow of the American Association for Artificial Intelligence and the Association for Computing Machinery, and the recipient of best paper awards from AAAI-96, KDD-04, ICML-05 and ACL-07.
