Anmerkungen:

• PROCESS OF DISCOVERING INTERESTING PATTERN AND KNOWLEDGE FROM LARGE AMOUNTS OF DATA

1. DESCRIPTIVES
2. PREDICTIVES
3. DOMAINS
   1. STATISTICS

      Anmerkungen:

      •  Statistics studies the collection, analysis, interpretation or explanation, and presentation of data  
   2. MACHINE LEARNING

      Anmerkungen:

      •  Machinelearning investigates how computers can learn (or improve their performance) based on data

   7. VISUALIZATION
   8. ALGORITHMS
   9. HIGH PERFORMANCE COMPUTING
4. PATTERNS CAN BE MINED DATA MINING FUNCTIONALITIES
   1. DISCRIMINATION

      Anmerkungen:

      • 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

      Anmerkungen:

      •  There are many kinds of frequent patterns, including frequent itemsets, frequent subsequences (also known as sequential patterns), and frequent substructures.  
      1. SUPPORT
      2. CONFIDENCE
      3. accuracy and coverage
   3. ASSOCIATIONS
   4. CORRELATIONS
   5. CLASSIFICATION AND REGRESSION

      Anmerkungen:

      •  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,   
   6. CLUSTERING ANALYSIS AND OULIER ANALYSIS

      Anmerkungen:

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

   4. KNOWLEDGE

Anmerkungen:

• ¿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.
