An Introduction to Cluster Analysis for Data Miningmachine learning, and data mining. The scope of this paper is modest: to provide an introduction to cluster analysis in the field of data mining, where we define data mining to be the discovery of useful, but nonobvious, information or patterns in large collections of data. Much of this paper is
DATA MINING TECHNIQUESData mining is the semiautomatic discovery of patterns, associations, changes, anomalies, and statistically signi cant structures and events in data. Traditional data analysis is assumption driven in the sense that a hypothesis is formed and validated against the data. Data mining, in contrast, is data driven in the sense that patterns are automatically extracted from data. The goal of this ...
