This paper describes applications of the optimized pattern discovery framework to text and Web mining. In particular, we introduce a class of simple combinatorial patterns over phrases, called proximity phrase association patterns, and consider the problem of finding the patterns that optimize a given statistical measure within the whole class of patterns(More)
Power distribution networks are designed for electrical power supply. In Power Line Communication (PLC) system, reflections caused by impedance mismatches deteriorate transmission characteristics in the high frequency. Estimation of Channel characteristics of power lines for PLC makes more efficient for design and operation of PLC networks. The authors(More)
