The notion of patterns in Data Mining
نویسندگان
چکیده
Several heterogeneous pattern types are available nowadays as a result of the different goals that a mining task tries to accomplish and of the application of Data Mining techniques over different domains. In this chapter we overview three popular pattern types, namely frequent itemsets and association rules, clusters and clusterings, and decision trees. We also adopt a pattern representation schema based on both extensional and intensional description of patterns and describe how the different pattern types are expressed with respect to this schema.
