  • Lovett Lecture on (Log Rank) Conjecture

    CSE Prof. Shachar Lovett was at MIT on Tuesday, Sept. 16, to give a talk on "New Advances on the Log Rank Conjecture." His colloquium was part of MIT's Theory of Computation lecture series. The log rank conjecture is one of the fundamental open problems in communication complexity. According to Lovett, the conjecture speculates that the simplest lower bound for deterministic protocols, the log-rank lower bound, is in fact tight up to polynomial factors.

    "A simple argument shows that there is always a deterministic protocol which uses r bits of communication, and until recently the best known bounds improved on this only by a constant factor," said Lovett (at right) in his abstract for the talk. "Recently, two new approaches allowed for improved bounds." One new approach was determined jointly by Lovett with Technion's Eli Ben-Sasson and Noga Ron-Zewi, a Technion-trained computer scientist now at Princeton's Institute for Advanced Study. They related it to a central conjecture in additive number theory, showing that "if it holds, then there are protocols which use O(r / log(r)) bits," i.e., at most a constant times (or factor) more than r/log r bits. The second approach outlined in Lovett's talk was based on discrepancy theory, giving an unconditional, upper bound of O(\sqrt{r} \log(r)) bits of communication. In addition to explaining the approaches and background, Lovett sketched the proofs and outlined "intriguing connections" to other central problems in complexity theory, including matrix rigidity, and two-source extractors. The Theory of Computation group, which organizes the colloquium, is part of MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), which spans two departments: Mathematics, as well as Electrical Engineering and Computer Science.

  • SoCal Theory Day 2014

    Be sure to mark Friday, October 17, 2014 on your calendar. Prof. Shachar Lovett is organizing SoCal Theory Day 2014. Reviving a tradition from long ago in CSE, SoCal Theory Day will host a series of external speakers in Theoretical Computer Science, as well as "ample time for mingling and networking." External speakers from Stanford, UCLA and Caltech will include: 

    • Amit Sahai, UCLA. Advances in Obfuscation.
    • Luca Trevisan, Stanford. Spectral graph algorithms for partitioning problems.
    • Chris Umans, Caltech. Approaches to bounding the exponent of matrix multiplication.
    • Ryan Williams, Stanford. Algorithms for circuits and circuits for algorithms: connecting the tractable and intractable

    The external speakers are pictured above right, l-r: Amit Sahai, Luca Trevisan, Chris Umans and Ryan Williams. Registration is required but free of charge (including free lunch for registered participants).

  • Single Model to Explain Visual and Auditory Precortical Coding

    CSE Prof. Gary Cottrell, Director of the multi-campus and interdisciplinary Temporal Dynamics of Learning Center (TDLC), will be the next speaker in a new lecture series sponsored by Dart NeuroScience. On Sept. 24 at 3pm in the Duane Roth Auditorium of the Sanford Consortium, Cottrell will explore how "a single model explains both visual and auditory precortical coding." It's part of a year-long dialogue on "the role of time and timing in learning, across multiple time scales, brain systems and social systems." According to TDLC, the Dart Neuroscience-TDLC Seminar Series is "a means of sharing a body of excellent science with the larger UCSD scientific and educational community" as well as the communities of both TDLC and Dart NeuroScience.

    According to Cottrell's seminar abstract, "precortical neural systems encode information collected by the senses, but the driving principles of the encoding used have remained a subject of debate. We present a model of retinal coding that is based on three constraints: information preservation, minimization of the neural wiring, and response equalization. The resulting novel version of sparse principal components analysis successfully captures a number of known characteristics of the retinal coding system, such as center-surround receptive fields, color opponency channels, and spatiotemporal responses that correspond to magnocellular and parvocellular pathways." Cottrell (at left) also notes that, "when trained on auditory data, the same model learns receptive fields well fit by gammatone filters, commonly used to model precortical auditory coding. This suggests that efficient coding may be a unifying principle of precortical encoding across modalities."

    The Sanford Consortium is located at 2880 Torrey Pines Scenic Drive in La Jolla. All of the seminars in the Dart NeuroScience-TDLC series in the 2014-2015 academic year will be available as live streaming webcasts for those unable to attend in person.

  • Computer Engineering Edges Higher in U.S. News Best Colleges for Undergraduates

    The 2015 Best Colleges Guide put out by U.S. News and World Report for undergraduate programs was published Sept. 9. The Jacobs School of Engineering ranks #15 among engineering programs at public institutions, and compared to all engineering schools, it ranks #26, unchanged from last year. US News also ranked computer engineering undergraduate programs, the only specialty among CSE programs to be ranked this year. On that front, computer engineering (for both ECE and CSE majors) edged up to #15, from #16 last year.

    Looking more closely at the computer engineering ranking, UC San Diego shared the #15 spot with two other institutions: Rice University, and the University of Southern California (USC). Both are private institutions, where undergraduate tuition and fees cost $40,566 and $48,280, respectively. By comparison, in-state tuition and fees are only $13,302 at UC San Diego. Even for out-of-state students coming to UCSD, tuition and fees are $12,000 less than at USC.

    The undergraduate ranking methodology is different from what U.S. News uses for its more widely-watched graduate school rankings. To assess undergrad programs, U.S. News relies solely on the judgments of deans and senior faculty at peer institutions (in our case, for universities where the highest engineering degree offered is a doctorate).
