Big Data

  • Modern database management systems (DBMS) have been designed to efficiently store, manage and perform computations on massive amounts of data. In contrast, many existing visualization systems do not scale seamlessly from small data sets to enormous ones. We have designed a three-tiered visualization system called ScalaR to deal with this issue.
  • BlinkDB is a database system that runs on top of Hadoop (MapReduce), running SQL queries and translating them into MapReduce jobs. The key idea is that rather than running queries over the entire data set, it runs queries on a random (precomputed) sample of the data, and uses sampling theory to estimate the true query answer.
  • At a major Computer Science and Artificial Intelligence event held May 31, 2012 at the MIT Stata Center, a new CSAIL initiative known as "bigdata@CSAIL" was announced by MIT president Susan Hockfield as Intel’s CTO, Justin Rattner announced that MIT would house a new Intel research center to focus on techniques for the science and engineering of big data -- the huge amounts of information generated by Web users and networked sensors. In addition, Massachusetts Gov. Deval Patrick announced the Massachusetts Big Data Initiative to investigate how big-data technologies can improve government.
  • Academic programs for graduate students in the field of computer science lead to the Master of Engineering, Master of Science, Engineer's, and either Doctor of Philosophy or Doctor of Science degree. 
  • Indyk/Katabi's sparse Fourier transform (SFT) has been named to MIT Technology Review’s 2012 list of the world’s 10 most important emerging technologies.
