Studies in multi relational extensions to rough set theory

Abstract

Current hardware and database technology allows efficient and inexpensive newlinestorage and access of vast amounts of data Data mining algorithms newlinesearch for patterns that may exist but are hidden among the vast amounts newlineof data One of the functions of data mining is classificationclassifying data newlineobjects examples into one of the predefined classes newlineRough Set Theory is one of the frameworks for classification of examples newlineusing inconsistent or incomplete information The Variable Precision newlineRough Set VPRS model is a generalized model of rough sets and allows a newlinecontrolled degree of uncertainty in the classification newlineThe limitation of the rough set model is that it analyzes data represented newlinein a single table Relational learning is learning from data represented in newlinemultiple tables newline newline newline
