   1. DISCRIMINATION

      Anotações:

      • DISCRIMINATION: COMPARISON OF FEATURES OF ONE CLASS DATA OBJETC AGAINST GENERAL FEATURES OF OBJECTS FROM ONE OR MULTIPLE CLASS OBJECTS CHARACTERIZATION:  summarizing the data of the class under study (often called the target class) in general terms  
   2. FREQUEN PATTERNS

      Anotações:

   5. CLASSIFICATION AND REGRESSION

      Anotações:

      •  Classification is the process of finding a model (or function) that describes and distinguishes data classes or concepts.  Regression analysis is astatistical methodology that is most often used for numeric prediction,

      Anotações:

      •  Unlike classification and regression, which analyze class-labeled (training) data sets, clustering analyzes data objects without consulting class labels.

   4. KNOWLEDGE

Anotações:

• ¿Interesante?:  (1) easily understood byhumans, (2) valid on new or test data with some degree of certainty, (3) potentiallyuseful, and(4) novel. A pattern is also interesting if it validates a hypothesis that the user sought to confirm.
