What's Going On: Teaching Data Science with Data Science

Call it (data science)2. In a February, 2017 seminar, Jose Luis Ambite described a project that uses data science—a concept unifying statistics, data analysis, related methods and their results—to teach biomedical researchers about data science.

What's Going On: Handling Sensor Changes and Failures

April 18, 2017

Craig Knoblock is best known for research on a large scale: semantic alignment of data in the widely used open-source tool called Karma, geospatial mapping techniques used by the Army in Iraq, collaboration on a commercial web data extraction platform, and recent, groundbreaking progress on international human trafficking with Pedro Szekely. In March this year, however, Knoblock presented work that appears to speak to a much smaller dimension: weather and water sensors.

Appears to, because as Knoblock made clear, improving sensor network resilience and scope builds directly on his previous work. Knoblock and his team sought to recreate sensor data after one unit fails or is swapped out for a more capable version. The challenge lies in inferring the missing data from information elsewhere in the network. The solution: building semantic descriptions of the underlying data, an approach similar to those Knoblock has used for geospatial mapping and human trafficking.

About 35 people attended the talk, part of ISI's "What's Going On" series, in Marina del Rey, California and Arlington, Virginia. "What's Going On" expands researchers' knowledge of efforts underway in, and fosters collaboration between, other Institute divisions and locations. Previous speakers have included Kristina Lerman on computational analysis of social media data, Jelena Mirkovic on life-experience passwords, Greg Ver Steeg on unsupervised learning and Andrew Schmidt on heterogeneous computing.

Knoblock's project, funded by the Defense Advanced Research Projects Agency, seeks to build survivable software that can interact reliably with sensors - particularly those for underwater vehicles. At present, replacing one sensor with another runs the risk of receiving similar data in a different format, changing the underlying database structure or being unable to exploit fresh information types generated by the newer model.Read More
