Operator ToolboxOperator Toolbox

This extension couples some useful additional operators together.

This extension adds a bunch of new operators to RapidMiner. They range from utility operators to improve the flexibility and usability of the process design, over additional outlier detection algorithm and additional performance criteria to advanced analysis methods like Local Interpretation or the SMOTE algorithm.

Since 2.6.0 the extension also adds new functions to the expression parser. These function can be used in operators like 'Generate Attributes', 'Filter Examples', 'Create ExampleSet'.

The extension provides the following additional functions to the expression parser:

  • Fuzzy Matching:

    • fuzzy_match ( Nominal first, Nominal second, Constant method )
