A Rough Set Approach for Generation and Validation of Rules for Missing Attribute Values of a Data Set
Data mining has emerged as most significant and continuously evolving field of research because of its ever growing and far reaching applications into various areas such as medical, military, financial markets, banking etc. One of the most useful applications of data mining is extracting significant and earlier unknown knowledge from real-world databases.
