Syntax

Description

DS2=dsClassMerge(DS, equivClass) returns a new DS2 which merges classes in DS based on equivClass.

• DS: Original dataset
• equivClass: A cell vector specifying which output to be combined. For instance, {[1 3], [2 4]} specifies outputs 1 & 3 to be combined into new output 1, and outputs 2 & 4 to be combined into new output 2.
• DS2: New dataset with the combined outputs

Example

DS=prData('iris');
DS2=dsClassMerge(DS, {[1,3], [2]})

DS2 = 

  struct with fields:

      dataName: 'iris'
     inputName: {'sepal length'  'sepal width'  'petal length'  'petal width'}
    outputName: {'Setosa & Virginica'  'Versicolour'}
         input: [4×150 double]
        output: [1×150 double]
