The classification technique analyzes records that are already known to belong to a certain class, and creates a profile for a member of that class from the common characteristics of the records. You can then use a data mining scoring tool to apply this classification model to new records, that is, records that have not yet been classified. This enables you to predict if the new records belong to that particular class.
The Classification mining function is widely used in Customer Relationship Management (CRM). Commercial applications of this mining function include credit card scoring, ranking of customers for directed mailing, the prediction of credit risk in new customers, and attrition prediction.
Intelligent Miner® uses the decision tree for classification models.
