  • Déjà Vu: CSE's Vianu Passes the Test of Time... Again

    For the second time in five years, CSE Prof. Victor Vianu is the recipient of the ACM PODS Alberto O. Mendelzon Test-of-Time Award. The annual award goes to the author or co-authors of a paper published in the proceedings of the Principles of Database Systems (PODS) ten years earlier. The award goes to the paper that had "the most impact in terms of research, methodology, or transfer to practice over the intervening decade." After winning the Test-of-Time Award in 2010, Vianu will be honored at the 2015 SIGMOD PODS conference in Australia this May, when he accepts his second Test-of-Time Award.

    The 2015 award will cite Vianu's influential 2005 paper, titled "Views and Queries: Determinacy and Rewriting." The paper explores a scenario that is not uncommon in query processing, security and privacy, data integration and query pricing. "The paper considers a seemingly simple question," explains Vianu, who will share the award with co-author Luc Segoufin from INRIA. "Suppose you know the answer to a query Q on a database and you wish to answer another query R. Does Q provide enough information to answer R? If so, how can the answer to R be obtained from Q?" According to Vianu, the problem turned out to be unexpectedly challenging even for the simplest queries used in relational database systems, and some of the basic questions raised in 2005 remain open today.

    [Editor's Note: Vianu is not the first CSE professor to receive two test-of-time awards from the same conference. For two years in a row, the International Symposium on Computer Architecture (ISCA) gave its Influential Paper Award in 2010 and 2011 to simultaneous multithreading-related papers by Dean Tullsen and colleagues 15 years earlier. The papers originally appeared in ISCA proceedings for 1995 and 1996.] 

    There is little doubt that Vianu's paper from ten years ago had an out-sized impact in the research arena. "This first paper spawned a whole line of follow-up research on this and related problems," says Vianu, noting that this year's Best Student Paper awardee at the 18th International Conference on Database Theory (ICDT) contributed to the same line of research (and cited Vianu's 10-year-old paper). "I think our paper received the award because the questions it raised were novel and widely relevant, and some of the answers it provided challenged conventional wisdom by going against widely accepted 'folklore' assumptions."

    (The Best Student Paper Award at ICDT 2015 will be awarded this March to "Asymptotic Determinacy of Path Queries using Union-of-Paths Views," by Nadime Francis, a graduate student at France's École Normale Supérieure de Cachan. Francis is also a collaborator with Vianu's co-author, Luc Segoufin, from the PODS paper.)

    In 2010 Vianu and his co-authors Dan Suciu and Tova Milo won the Mendelzon Test-of-Time Award for their work a decade earlier on type-checking for XML transformation languages. Vianu's paper studied the problem of checking whether or not an XML transformation is well-typed -- which would be essential for manipulating XML documents. The paper proved that typechecking for k-pebble transducers is decidable and, consequently, it could be performed for a broad range of XML transformation languages.

    Victor Vianu received his Ph.D. in Computer Science from the University of Southern California in 1983 and joined UC San Diego in 1984. Aside from UCSD, he has taught at the Ecole Normale Superieure and Ecole Nationale Superieure des Telecommunications in Paris, as well as the Sorbonne. He has spent numerous sabbaticals as an invited professor at INRIA, where he now holds an International Chair. Vianu's interests include database theory, computational logic, and Web data. His most recent research focuses on specification and verification of data‐driven Web services and workflows. Vianu's publications include over 100 research articles and a graduate textbook on database theory.

  • Theory of Computation Expert to Give Inaugural Talk in New Lecture Series

    On Friday, Jan. 30 at 11am, CSE Profs. Mohan Paturi and Russell Impagliazzo will host computer scientist and mathematician Avi Wigderson, one of the most prolific and influential researchers in the theory of computation. Wigderson was invited to speak in the department's colloquium and Distinguished Lecture Series. His topic: "Randomness". The talk is aimed at a general scientific audience. Wigderson is a professor in the School of Mathematics at the Institute for Advanced Study, best known as the longtime intellectual home of Albert Einstein in the U.S. (from 1933 until his death in 1955), located in Princeton, NJ.

    According to the abstract, "Is the universe inherently deterministic or probabilistic? Perhaps more importantly - can we tell the difference between the two? Humanity has pondered the meaning and utility of randomness for millennia.  There is a remarkable variety of ways in which we utilize perfect coin tosses to our advantage: in statistics, cryptography, game theory, algorithms, gambling... Indeed, randomness seems indispensable! Which of these applications survive if the universe had no randomness in it at all? Which of them survive if only poor quality randomness is available, e.g. that arises from "unpredictable" phenomena like the weather or the stock market?" 

    Wigderson goes on to note that a "computational theory of randomness, developed in the past three decades, reveals (perhaps counter-intuitively) that very little is lost in such deterministic or weakly random worlds. In the talk I'll explain the main ideas and results of this theory." 

    Wigderson has made fundamental contributions to circuit complexity, parallel algorithms,cryptography (in particular, to zero-knowledge proofs and private multi-party computation), the role of randomness in computation, proof complexity, and connections between complexity and combinatorics. He earned his Ph.D. in computer science at Princeton University in 1983, studying with Prof. Richard Lipton.  He was a professor at Hebrew University from 1986 to 2003, and has been on the faculty of the Institute for Advanced Study since 2003. Among many other honors, Wigderson is the recipient of the Nevanlinna Prize (1994), awarded every four years for outstanding contributions in mathematical aspects of information sciences; and the Gödel Prize (2009), jointly with Omer Reingold and Salil Vadhan, for their work on the zig-zag graph product. In 2013 Wigderson was elected to the National Academy of Sciences. 

  • CSE Society Stages CSE Day 2015

    The Computer Science and Engineering Society (CSES) and its members turned out in force on Thursday, Jan. 22, for the 2015 version of the society's annual CSE Day event. Organizers estimate that roughly 250 students consistently attend at least one of the day's events (depending on their class schedules). Talks, activities and panel discussions throughout the day aimed to "inform students about the paths available to them in the computer science field by having them interact with students, alumni and faculty in the CSE Department, and members from industry." Sponsors of the event included Qualcomm, Microsoft, Google, ViaSat, and Visa (which also supplied one of its forensic investigators, John Camacho, to deliver a Tech Talk on enterprise-wide, risk-based security).

    Computer security was also on display when Prof. Stefan Savage (pictured at right) delivered a talk on "Buying Drugs for Science: Addressing the Economics of Cybercrime." Savage focused on the social and economic forces driving today's Internet attacks and deconstructing the underlying value chain for attackers. He sketched a picture of "economically-motivated, advertising-based e-crime." Savage and his collaborators spent roughly a year getting permission to use research funds to purchase $50,000 worth of counterfeit drugs and other merchandise sold through a patchwork of entities that make up the cyber-criminal ecosystem. The study, which included 600 orders of illicit drugs, turned up amazing evidence of the role that one type of pharmaceutical plays in the ecosystem: "Erectile dysfunction counterfeit drugs account for 75 percent of e-crime demand," said Savage, "and 80 percent of revenues." Tellingly, he added, between 20 and 40 percent of all sales of Viagra are ordered from consumers' spam folders, i.e., those consumers had to go into their spam folder to click on an offer of Viagra (usually at 20 percent of the regular price in the U.S.). The professor, who also directs the Center for Networked Systems, showed CSE students an example of ingenuity in packaging: the researchers received a shipment from Bangladesh that was supposed to have been for counterfeit RU-486 abortion pills. Instead they received an ornate woven textile that looked like a miniature carpet. With a little effort, they split apart the textile at the seams, only to find the pills stitched into the fabric.

    Other activities during the day included Startup 101, a panel on the growing phenomenon of computer science and engineering-based startup companies. Speakers included Moxie Center executive director Jay Kunin, who mentors students in the 40 companies already admitted to the Moxie Incubator, as well as two student entrepreneurs: Chesong (Daniel) Lee, co-founder of the earphone company called Hush, which raised nearly $600,000 on Kickstarter versus the $100,000 they were seeking; and Joseph Le, a second-year computer science student whose company StudentHero connects high school students to summer internships.

    Another popular session was the Alumni Panel, which gaves current students an oppportunity to ask the alumni for tips on interviewing, presenting, seeking internships, and so on. Speakers included: Patrick Johnson (BS '07), now a software engineer at Google; Qualcomm staff engineer and CSE lecturer Garo Bournoutian (BS '05, PhD '14); McKenzie Velia (BS '13), who parlayed a summer internship to a year-long internship and most recently, a full-time job working on network security, all at ViaSat; and CSE Alumni Board member Justin Allen (BS '10), who recently joined WebAction, a Palo Alto-based company in the real-time data streaming space.

    Among their recommendations in response to student questions:
    - Go to career fairs.
    - Get involved in student organizations (and student government, as Garo Bournoutian did as president of the Graduate Student Association).
    - Make yourself known to faculty members; they are often asked to recommend a student for hire.
    - Participate in the Jacobs School's Team Internship Program (like McKenzie Velia did at ViaSat).
    - Attend any event where you can get feedback and critique of your resume.
    - Consider studying a year abroad, preferably as a sophomore. (Justin Allen spent his year abroad in Scotland, and it was invaluable.)
    - Become a CSE Tutor: it's rewarding and looks great on your resume.

  • Moxie Center Stages Open House and Pitchfest

    CSE students with an idea for a new app or business venture may want to attend the Moxie Center for Student Entrepreneurship's Open House this Thursday, Jan. 15. The center is also inviting CSE and other UC San Diego students to participate in a PitchFest during the Open House, delivering a maximum 60-second pitch for a business idea. The Open House starts at 11:30am in room B210 in the basement of the CSE Building. The Pitchfest begins at 12 noon.

    The event will give students an opportunity to meet fellow entrepreneurs (or entrepreneurs-to-be), including representatives from many of the 40 startups now part of the Moxie Incubator. (All teams in the incubator are allowed to compete for the annual Zahn Prize, which awards up to $20,000 to winning startups.) No applications or sign-ups are required for the Thursday event, but attendees are invited to deliver a one-minute pitch with the idea for a startup. According to the Moxie Center, "a business pitch is not about technology, but the value it would bring to customers." Attendees are also allowed to sit back and watch the pitches, then vote for the audience favorite (who is awarded a $50 prize). The judges' selection will walk away with $100. The event is open to students, staff, faculty and community members, but the Pitchfest competition is limited to UC San Diego students only.
