  • NSF Awards Database Grant to Improve Efficiency of Sensor Data Analytics

    September 1 was the start date of an important new project for two faculty members in Computer Science and Engineering. CSE Prof. Yannis Papakonstantinou (near right) is principal investigator on the $1.1 million, three-year project funded by the National Science Foundation to build Plato, a model-based database for compressed, spatiotemporal sensor data. Co-PI on the project is CSE Prof. Yoav Freund (far right).

    At it stands, analytics for sensor data is not as productive as tools for non-sensor business intelligence platforms. The reason? Database technology and sensor data processing currently don't mix, at least not very well, part because SQL databases of spatiotemporal sensor data fail due to the lack of critical abstractions (real-world models) that capture the stochastic processes which generate measurements. This is particularly true when dealing with many types of sensor data, or when mixing sensor data with metadata from conventional databases, or when many different types of analysis are required. Furthermore, anyone handling this type of data must be simultaneously an expert in signal processing, statistics, and the management of big data.

    So the Plato system will allow analysts to develop quickly declarative queries that can be automatically optimized. "By doing so, the project will deliver the envisioned productivity gains," says Papakonstantinou. "Plato will also lower the technical sophistication required of users, therefore enabling many scientists and domain specialists to work with sensor-data analytics." While Papakonstantinou focuses on designing a model-aware data model and query language features that combine conventional SQL querying with statistical signal processing, co-PI Yoav Freund will develop learning algorithms that learn the model components of reduced-noise, additive model representations. Other algorithmic work will involve query processing directly on compressed representations rather than the original data, and semiautomated algorithms to further compress the model representations in light of dependencies between the models.

    The researchers are also planning to use the CSE-built UC San Diego Energy Dashboard (pictured at left) and the Qualcomm Institute-based Data E-platform Leveraged for Patient Empowerment and Population Health Improvement (DELPHI) as primary use cases for the new database system as it develops.

  • CSE Alumna and Ph.D. Student Launch Kickstarter Campaign for Game to Teach Coding

    The team of CSE students and colleagues who set up a company to help teach kids how to code has turned to the Kickstarter crowdfunding platform to raise funds. On September 2, the startup company ThoughtSTEM launched a Kickstarter campaign to raise $50,000 for further development of the CodeSpells educational videogame, and within a few hours, it had already topped $7,500. CodeSpells was originally built by recent CSE Ph.D. graduate Sarah Esper (far right) and CSE Ph.D. student Stephen Foster (near right) as a vehicle to teach software programming to young children. Foster and Esper later teamed with UCSD Ph.D. bioengineering student Lindsey Handler to create the company ThoughtSTEM to provide after-school programs and summer camps where they used an early prototype of CodeSpells to teach coding.w

    CodeSpells allows the player to craft their own magic spells in what ThoughtSTEM calls "the ultimate spellcrafting sandbox." The program uses an intuitive drag-and-drop language that even children can use. Students can learn to code, syntax-error free, using a Blockly spell-crafting interface that has all the tools available in Javascript. When they've learned all the programming concepts from Blockly, students can move on to typing Javascript code. If the Kickstarter campaign raises the minimum $50,000 by early October, ThoughtSTEM will undertake a makeover of CodeSpells' look and feel, gameplay, and coding interface. The game will eventually allow student wizards to master each of five elements -- earth, fire, water, air, and life -- but initially only with one element of gameplay, earth, is available (pictured at left). The Kickstarter funding would allow ThoughtSTEM to develop three more elements, and to enhance the overall game. The alpha version of CodeSpells will be released to anyone providing $80 or more in funding on Christmas Day of 2014, followed by the beta release in June 2014 to backers at the $30-and-up level. Feedback from those early users will help the team improve the gameplay, and if funding is available beyond 2015, ThoughtSTEM will release the life element of the game, featuring creatures, plants and non-player characters, in 2016.

  • 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.

  • CSE Professor Elected to Academia Europaea

    CSE Prof. Victor Vianu is one of only 16 new members elected to the Informatics section of the Academia Europaea, the Academy of Europe, which is their version of the combined U.S. National Academies. The Academy has 3000 members of which 229 elected this year across all areas. "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 computater science. Through November 2018, Vianu also holds a five-year INRIA International Chair at INRIA-Saclay, just southwest of Paris. 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.
