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.

Currently the extension provides the following Operators:

  • Blending

    • Calculate Overlaps

    • Collect and Persist

    • Extract Statistics

    • Filter Attributes with Missing Values (new in 1.6.0)

    • LDA model now has a overview over various topic diagnostics measures.
      • Accessible over the LDA model table renderer in the result view.
    • Parameters seed, thinning, burnin and iterations for the LDA model can now be set by the application parameters of the Apply Model operator
    • Added perplexity as a performance measure of LDA.
    • Added an option to get the mallet logging into the RapidMiner log panel
    • Bugfix for meta data when storing a LDA model
    • LDA is now correctly using the token text of a document, not the display text

Version 1.2.0 (2018-06-08)

  • New operator Generate Session ID
  • Bugfix for LDA Model
    • Its now possible to use Generate Prediction Ranking together with LDA models

Version 1.1.0 (2018-05-16)

  • Dictionary-Based Sentiment:
    • Moved operator to text processing folder

    • Hence Apply Dictionary-Based Sentiment is now deprecated
  • LDA
    • Bugfix for the calculation of the alpha sum parameter
    • Correct the name of the confidence roles, so that RapidMiner can automatically identify the attributes as confidence attributes.
