Data Mining operations

Data Mining methods may be classified by the function they perform or according to the class of application they can be used in

• Predictive modeling
  • Classification
    Stored data is used to locate data in predetermined groups Data Mining tools have to infer a model from the database.This requires one or more classes
    • discriminative
    • generative
  • Regression,curve fitting
• Segmentation (Clustering)
  Data items are grouped together according to logical relationships or consumer preferences.It involves processes of creating a partition so that all the members of each set of the partition are similar according to some metric
  • distance based methods
  • model-based clustering
  • partition-based methods
• Dependency Modeling

  • Probabilistic Graphical Modeling(Bayesian networks)
• Summarization
  • association rules Data can be mined to identify associations
• Change and deviation detection
