This extension enables Predictive Analytics capability to FlexRule platform. The extensions adds both expression commands Toolbox commands.

train

Trains and builds a predictive model using data.

 train (list, algorithm, class, options)
  • algorithm:
    • PMML v4.3 (Read Details)
      • Regression Model
      • Generalized Regression Model
      • Naive Bayes Model
      • Classification and Regression Tree Model
      • Support Vector Machine Model
      • Random Forest (Mining Model)
      • Neural Networks Model
      • Clustering Model
      • Gradient Boosting Machine Model (Mining Model)
      • Association Rules Model
      • K-Nearest Neighbors Model
    • c45: Decision Tree
    • nb: Naive Bayes
  • class: attributes name that is the class name (i.e. attribute or field of data that going to be the result of prediction)
  • options: Algorithm options if it is available
  • Return: analytic’s trainedModel

predict

Uses a trained model to predict results for a data record.

 predict (trainedModel, data, options)
  • trainedModel: the train function result.
  • data: Situation that requires the prediction. (i.e. a JSON with fields of value)
  • options: Algorithm options if it is available

extractRules

Extracts rules for Decision Tree.

 extractRules (trainedModel, type)
  • type: if, elseIf
  • Retrun: list of rules that are bases of the trained model

Examples

The following examples are available by default when you open FlexRule Designer.
