متن کاملKnowledge Discovery and Data Mining in Databases
Knowledge Discovery in Databases (KDD) is the process of automatic discovery of previously unknown patterns, rules, and other regular contents implicitly present in large volumes of data. Data Mining (DM) denotes discovery of patterns in a data set previously prepared in a specific way. DM is often used as a synonym for KDD. However, strictly speaking DM is just a central phase of the entire pr...
