=== 3.3.0 ===

Warning: This version is not backwards compatible, since column names changed from v 3.2.0 to 3.3.0 to have one scheme.

  •  Changed the role of outlier scores in all Detect Outlier operators. Its now a confidence (score).
  • Changed the name of the generated score attribute in all Detect Outlier operators. It is now "score"
  • Added a new operator "Generate Outlier Flag" which allows you to discretize the score attributes.

 

=== 3.2.0===

* Added a new operator Detect Outliers (Isolation Forest), which was previously part of Operator Toolbox

* Trees in isolation forests are now trained on a bootstrapped subset of the original data

* Trees in isolation forests can now define the number of features considered in every tree.

=== 3.1.0 ===

* Added a new operator Detect Outliers (Univariate), which was previously part of Operator Toolbox

* Added a new operator Detect Outliers (Time Series)

=== Version 3.0.1 ===

  • Added new operator Detect Outliers (Clustering) which wraps the three outlier detection algorithms
  • Detect Outliers (Clustering) provides a model to be applied on new data.
  • Added a new operator Detect Outliers (rPCA), which also provides a model.
  • Switched to an up-to date LibSVM version. Robust one-class is thus not available anymore. Results may differ slightly.
  • Switched the lib for RNN operator, results may differ.

=== Version 3.0.2 ===

  • Fixed minor bugs
