  • Three typical types of Data Mining applications

    Three typical types of Data Mining applications:
        Classification
        Regression
        Clustering

    Classification
    In a classification type problem, we have a variable of interest which is categorical in nature. For example, this could be:
        Classification of credit risk, either good or bad
        Classifying patients as high risk for heart disease
        Classifying individuals as high risk for fraudulent behavior

    The goals of the classification problem can include:
        Finding variables that are strongly related to the variable of interest
        Developing a predictive model where a set of variables are used to
        Classify the variable of interest

    Regression

    In a regression type problem, we have a variable of interest which is continuous in nature. For example, this could be:
        A measurement for a manufacturing process
        Revenue in dollars
        Decrease in cholesterol after taking medication

    The goals of the regression problem are similar to classification and can include:
        Finding variables that are strongly related to the variable of interest

        Developing a predictive model where a set of varicbles are used to
      predict the variable of interest

    Clustering

    In a clustering type problem, there is not a traditional variable of interest. Instead, the data needs sorted into cluster. For example:
      Clustering indibiduals for a marketing campaign
      Clustering symptoms in medical research to find relationships
      Finding clusters of bands, based on customer responses

    The goals of cluster analysis problem can include:
      Finding variables that are most highly influence cluster assignment
      Comparing the clusters across variables of interest
      Assigning new cases to clusters and measuring the strength of cluster membership
