  • Repeating EventMeet USC: Admission Presentation, Campus Tour, and Engineering Talk

    Wed, May 29, 2019

    Viterbi School of Engineering Undergraduate Admission

    Workshops & Infosessions


    This half day program is designed for prospective freshmen (HS juniors and younger) 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!

    Title:
    Understanding and Optimizing Video Delivery

    Abstract:
    In this work, we strive to understand and optimize the performance of systems which serve video over the Internet. Towards this end, we make the following three contributions. First, we perform a systematic study of the video management plane -- the systems which form the video delivery pipeline. Second, we propose an approach called Oboe to improve the performance of client side video players by tuning Adaptive Bitrate Algorithms to the characteristics of a network. A range of different algorithm when augmented with Oboe improve their performance by up to 25%. Finally, we propose a caching algorithm called AVC which is specifically tailored for video workload. AVC outperforms state of the art caching algorithms by exploiting various properties of adaptive bitrate video. In particular, a LRU cache requires 3x the memory used by AVC to match its performance.

  • NL Seminar-Quantifying the morphosyntactic content of Brown Clusters

    Thu, May 30, 2019 @ 11:00 AM - 12:00 PM

    Information Sciences Institute

    Speaker: Manuel Ciosici, Aarhus University

    Talk Title: Quantifying the morphosyntactic content of Brown Clusters

    Series: Natural Language Seminar

    Abstract: Brown and Exchange word clusters have long been successfully used as word representations in Natural Language Processing NLP systems. Their success has been attributed to their seeming ability to represent both semantic and syntactic information. Using corpora representing several language families, we test the hypothesis that Brown and Exchange word clusters are highly effective at encoding morphosyntactic information. Our experiments show that word clusters are highly capable of distinguishing Parts of Speech. We show that increases in Average Mutual Information, the clustering algorithms' optimization goal, are highly correlated with improvements in encoding of morphosyntactic information. Our results provide empirical evidence that downstream NLP systems addressing tasks dependent on morphosyntactic information can benefit from word cluster features.


    Biography: Manuel is a soon to graduate Ph.D. student at Aarhus University, Denmark. His research is focused on understanding the kinds of information encoded in word representations and how that information can be used in downstream NLP applications.
