Meet USC: Admission Presentation, Campus Tour, & Engineering TalkWed, Feb 18, 2015
Viterbi School of Engineering Undergraduate Admission
Receptions & Special Events
This half day program is designed for prospective freshmen and family members. Meet USC includes an information session on the University and the Admission process, a student led walking tour of campus, and a meeting with us in the Viterbi School. During the engineering session we will discuss the curriculum, research opportunities, hands-on projects, entrepreneurial support programs, and other aspects of the engineering school. Meet USC is designed to answer all of your questions about USC, the application process, and financial aid.
Reservations are required for Meet USC. This program occurs twice, once at 8:30 a.m. and again at 12:30 p.m. Please make sure to check availability and register online for the session you wish to attend. Also, remember to list an Engineering major as your "intended major" on the webform!Location: Ronald Tutor Campus Center (TCC) - USC Admission Office

Creativity in People and Computers
Wed, Feb 18, 2015 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Paul Thagard, University of Waterloo
Talk Title: Creativity in People and Computers
Abstract: Abstract: An idea is creative if it is new, valuable, and surprising. This talk will describe neural mechanisms for human creativity, including multimodal representations, binding of representations into new ones, and competition among them to become conscious. These mechanisms contrast with current computational models of creativity such as Chef Watson, but suggest how computers might become more creative.
Biography: Paul Thagard is Professor of Philosophy at the University of Waterloo.
His most recent books are The Brain and the Meaning of Life (Princeton University Press, 2010) and The Cognitive Science of Science: Explanation, Discovery, and Conceptual Change (MIT Press, 2012).
Host: Greg Ver Steeg

Talk Title: Turning Memory into Bandwidth via Wireless Edge Caching: Fundamental Limits and Practical Challenges
Series: CommNetS
Abstract: Video is responsible for 66% of the 100x increase of wireless data traffic predicted in the next few years. Traditional methods for network capacity increase are very costly, and do not exploit the unique features of video. This talk gives a survey of a novel transmission paradigm based on the following two key properties: (i) video shows a high degree of asynchronous content reuse, and (ii) storage is the fastest-increasing quantity in modern hardware. Based on these properties, we suggest caching at wireless edge, namely, caching in helper stations (femto-caching) and/or directly into the user devices. We study two fundamentally different network structures: shared link caching networks and device-to-device (D2D) caching networks.
First, we present results based on network coded multicast delivery and/or D2D transmissions that show a âMooreâs lawâ for throughput: namely, in a certain regime of sufficiently high content reuse and/or sufficiently high aggregate storage capacity (sum of the storage capacity of all the users) in the network, the per-user throughput increases linearly, or even super-linearly with the cache size, and it is independent of the number of users for large network size, despite the fact that these users make independent and individual video files requests, i.e., the system does not exploit the naive broadcasting property of the wireless medium to send the same source to everybody. On the other hand, for both considered networks, we also provide information theoretic converse, by using which, we show that the proposed schemes achieves the order-optimal capacity. Then, we present the practical challenges and limitations of the achievable schemes. To overcome these challenges, for both network structures, we design novel polynomial-time complexity algorithms, which achieves near optimal performance such that they preserve the promised âMooreâs lawâ for throughput under realistic network parameter regimes.
Biography: Mingyue Ji is a final year PhD candidate at Ming Hsieh Department of Electrical Engineering, University of Southern California (USC). His adviser is Professor Giuseppe Caire, and he is also very fortunate to collaborate with Professor Andreas Molisch during his PhD study. Prior to USC, he worked as a research engineer and finished his Master thesis at the Access Technologies and Signal Processing Group in Ericsson, Stockholm, Sweden. He also obtained his Master of Science (MS) Degree in Electrical Engineering at Royal Institute of Technology (KTH), Sweden, and obtained his Bachelor Degree in Communication Engineering at Beijing University of Posts and Telecommunications (BUPT), China.
