  • Best Industry Paper Awarded to CSE Alumna at KDD 2014

    Over 2,000 people attended the 20th ACM SIG International Conference on Knowledge Discovery and Data Mining (KDD 2014), a premier interdisciplilnary conference that brings together researchers and practitioners from data science, data mining, knowledge discovery, large-scale data analytics, and big data.

    Best paper awards were handed out to academic and industry papers, and this year's Industry & Government award went to CSE alumna Diane Hu (pictured far right, receiving the award). Hu and her co-authors were cited for their paper, "Style in the Long Tail: Discovering Unique Interests with Latent Variable Models in Large Scale Social E-commerce." The CSE alumna (M.S. '09, Ph.D. '12 under CSE Prof. Lawrence Saul, her advisor) and her co-authors, Rob Hall and Josh Attenberg, all work at Etsy, Inc., the e-commerce website that bills itself as "the world's most vibrant" marketplace for handmade or vintage items and supplies. Etsy attracts developers with its slogan, "We believe in code as craft."

    In the award-winning paper, Etsy data scientist Hu and her colleagues tackle the challenge of matching buyers to products "as the size and diversity of the marketplace increases." With over 30 million diverse listings, Etsy must deal with the problem of capturing shoppers' aesthetic preferences in order to steer them to items that fit their eclectic styles. In her talk, Hu described the methods and experiments underlying two new style-based recommendation systems on the Etsy site. One is called Latent Dirichlet Allocation (LDA). LDA discovers trending categories and styles on Etsy, which are then used to describe a user's "style" profile. Hu and her colleagues also explored hashing methods to perform fast nearest neighbor search on a map-reduce framework, in order to efficiently obtain recommendations. "These techniques have been implemented successfully at very large scale," concluded Hu, "substantially improving many key business metrics."

    Knock It Off

    Current CSE faculty and students were also represented on the KDD program. 5th-year Ph.D. student Matthew Der (M.S. '13, Ph.D. '15 expected) collaborated on a paper with his three advisors – Lawrence Saul, Stefan Savage and Geoffrey Voelker – called, "Knock It Off: Profiling the Online Storefronts of Counterfeit Merchandise." The team developed an automated system for classifying illegal online storefronts according to which "affiliate program" (or business) runs the store. Their approach was to extract features from the HTML source code of the Web pages; these features capture the similar underlying structure of storefronts that link to the same affiliate program. Experiments showed that the system is highly accurate in classifying the storefronts of "44 distinct affiliate programs that account, collectively, for hundreds of millions of dollars in illicit e-commerce," according to the paper.

  • CSE Professor Elected to Academia Europaea

    CSE Prof. Victor Vianu is one of only 16 new members from the Informatics section to be elected members of the Academia Europaea, the Academy of Europe, which is their version of the combined U.S. National Academies. "It was indeed a nice surprise," says Vianu, "especially since very few non-Europeans are elected." In announcing the honor, the Academia noted Vianu's fields of scholarship in database systems and theory, computational logic, and automatic verification. While he has been a professor at UC San Diego since 1983, since then he has also taken sabbaticals at INRIA, France's public research institution dedicated to computational science and mathematics. Through November 2019, Vianu also holds a six-year INRIA International Chair at INRIA-Saclay-Ile-de-France, just southwest of Paris, in a building appropriately named after Alan Turing. A total of 229 new members were named by the Academia Europaea in 2014. Vianu's past honors include being elected a Fellow of the American Association for the Advancement of Science in 2013, the 2010 ACM PODS Alberto O. Mendelzon Test-of-Time Award, and being elected Fellow of the Association for Computing Machinery in 2006. 

  • Ph.D. Student Wins Science Policy Fellowship

    CSE graduate student Natalie Larson recently received a three-year Department of Defense SMART fellowship to finish her Ph.D. Now she has been selected as one of three inaugural IR/PS Science Policy Fellows, a program launched for the 2014-'15 academic year by the School of International Relations and Pacific Studies. Applicants had to be graduate students enrolled in UC San Diego's Jacobs School of Engineering, Scripps Institution of Oceanography, or School of Medicine. In addition to a $1,000 stipend (which Larson will spend on policy-related research and travel), the fellowship gives awardees access to IR/PS personnel to explore the policy implications of their work. In Larson's case, her Ph.D. work is in the area of Internet measurement.  "It has a strong policy component because traffic management practices of network service providers, transit providers and content distributors can heavily influence Internet topology and performance.  Policymakers are still trying to learn enough about the Internet ecosystem to develop regulations regarding such entities that will protect consumers and innovation without hindering investment," explains Larson.  "The IR/PS Science Policy Fellows Program will allow me to work directly and closely with policy experts."

    Last week Larson also learned that she was selected to receive a Student Travel Grant to the 2014 Internet Measurement Conference, set to take place in Vancouver, Canada in November. While she doesn't have a paper at IMC, she expects to be working on topics that may come up at the conference, including tomographic techniques to localize Internet congestion and infer its causes.

  • From Flash Memory Security to Machine Consciousness

    The 20th anniversary of the Neuromorphic Cognition Engineering Workshop took place last month, and participants spent three weeks in Telluride, CO, working on ambitious projects in neuromorphic engineering. Stephen Deiss was a participant in the first Telluride workshop in 1994 and he was back at the 2014 workshop, this time as a staff engineer from CSE's Non-Volatile Systems Laboratory (NVSL). Working under CSE Prof. and NVSL Director Steven Swanson, Deiss supports projects characterizing flash memory security and new user tools for building simple electronic devices.

    "The early workshops focused on bringing people up to speed on the neuroscience of sensory and motor systems, as well as analog VLSI designs to mimic those neural circuits," recalls Deiss, who previously developed the 'Silicon Cortex' board, one of the first neuromorphic hardware platforms for testing analog VLSI neuromorphic chips. "That component is still very much alive at Telluride today, but in recent years the field has started to focus much more on capturing all aspects of cognition." 

    Participants in the 2014 workshop covered areas ranging from EEG capture and interpretation, robotics from biological, dynamical systems and neuroengineering perspectives, wearable navigation aids, vision systems, and fundamental neuroscience from synapses to cortical integration processes. CSE's Deiss also participated in the "Neuromorphic Olympics," a competition involving small 'pushbots' and a Sumo wrestling-type game in which the robots compete to push each other out of a circle. Deiss finished in third place.
