Abstract
This paper considers the problem of detecting dependencies among data streams and presenting the results in a mobile data mining system. It particularly focuses on the systems issues addressed by MobiMine, a system for mining financial data streams from PDAs. It presents an overview of the MobiMine, explains the two algorithmic techniques (correlation and conditional probability rules) used for detecting dependencies between a pair of stocks, identifies the systems challenges, and offers solutions. The paper also presents experimental results supporting MobiMine's scalable performance.
