Data Mining (Classifier|Classification Function)
A classifier is a Supervised function (machine learning tool) where the learned (target) attribute is categorical (quot;nominalquot;) in order to classify. It is used after the learning process to classify new records (data) by giving them the best target attribute (prediction). Rows are classified into buckets. For instance, if data has feature x, it goes into bucket one; if not, it goes into bucket two.
