System Bits: Dec. 1

System-Level Design The curse of dimensionality; new particle discovered; battling crop disease with smartphones. Extracting the right information in large data setsWhen solving complex scientific problems, researchers sometimes encounter what is called the curse of dimensionality, that is, they have so much data that they cannot efficiently analyze it. Large data sets can also be expensive and time consuming to acquire, so it is critical to gather only what is necessary. To this end, University of Illinois Assistant Professor Yihong Wu, and Professor Tsachy Weissman of Stanford University were awarded $500,000 from the National Science Foundation to identify optimal algorithms that efficiently extract the relevant information from large data sets. The researchers explained that with advanced technology and data acquisition methods, data sets can be larger than they ever have been, and…
