For the past two decades, fractals (e.g., the Hilbert and Peano space-filling curves) have been considered the natural method for providing a locality-preserving mapping. The idea...
Data mining applications analyze large collections of set data and high dimensional categorical data. Search on these data types is not restricted to the classic problems of minin...
We are interested in capturing time series generated by small wireless electronic sensors. Battery-operated sensors must avoid heavy use of their wireless radio which is a key cau...
Determining relationships such as functional or inclusion dependencies within and across databases is important for many applications in information integration. When such informa...
Web crawlers generate significant loads on Web servers, and are difficult to operate. Instead of repeatedly running crawlers at many "client" sites, we propose a central...
