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:

    • added throughput port for the input file object
    • changed the "id" attribute to be called "Sheet Number", to have an id role and to start counting at 1 (as the Read Excel operator also starts with 1), operator is not compatible with earlier processes anymore!
    • added the parameter "file name", similar to the ReadExcel operator
  • Improvements of the Replace Rare Values operator
    • Operator now cleans the mapping of the selected attributes
    • Removed "create view" parameter (which have had no effect)

  • Enhancements
    • Added appropriate aylien and meaning cloud icons
    • Fixed a "unknown error message" in Apply Model (Documents)
    • Added new UserError to Tukey Test Preprocessing model, in case the attribute type is wrong.

Version 2.0.1 (2019-04-23)

  • Enhancements:
    • Extract Sentiment has now the option to use custom words in dictionary based methods and scores for dictionary based methods are now normalized. The max(abs(score)) is defined as 1.
  • Bugfixes:
    • Extract Sentiment: Fixed a bug in SentiWordNet where Positivity and Negativity was wrongly calculated

    • Append (Superset): BugFix when matching attributes of mismatched types (Real and Integer) they were always converted to polynominal.

Version 2.0.0 (2019-03-26)

  • New operator: Optimize Thresholds
    • automatically determines the best threshold for a binominal classification problem
  • New operator: Extract Macro (Format)
    • same functionality as Extract Macro, but you can specify the format of numbers and dates
  • New operator: Extract Sentiment
    • extracting sentiment from text inputs using dictionary and API based methods (Vader, Sentinet, Aylien, MeaningCloud)
  • New operator: Append (Superset)
    • same functionality as Append, but you can append ExampleSets with different attributes
  • Enhancements:
    • Restructured the blending operator folder
      • added subfolders 'Tables' and 'Attribute Generation'
      • changed the color of the operators in these subfolders
    • Added several tags for Replace Rare Values
    • Merge operator:
      • Corrected Meta Data
      • Changed that in case attributes or annotations are renamed, that the first occuring attribute/annotation is also renamed
    • Bugfix in Phonetic Encoding and Extract Statistics in rare cases of attribute selection

Version 1.8.0 (2019-02-08)

  • Get Decision Tree Path now also works for regression trees
  • Bugfix for SMOTE operator when not using normalized distances

    • Both operators are deprecated now
    • Smile library dependency is removed

    • Updated default optimization interval of the hyperparameters in both LDA operators from 50 to 10
    • Added AlphaSum, Beta and BetaSum to the performance vector output.
    • Bugfix in case numerical meta data element is missing
    • Bugfix that causes the LDA to not respect preprocessing step like Filter Stopwords
  • Bugfix TSNE operator: fixed a bug in handling special attributes
  • Bugfix in Check Model Conformance, that nominal attributes were checked if fail on error is true, even if check nominals is false
