KNIME WEKA nodes (3.7) version 4.0.0.v201905311239 by KNIME AG, Zurich, Switzerland
Class implementing minimal cost-complexity pruning. Note when dealing with missing values, use "fractional instances" method instead of surrogate split method. For more information, see: Leo Breiman, Jerome H

(based on WEKA 3.7)
For further options, click the 'More' - button in the dialog.
All weka dialogs have a panel where you can specify classifier-specific parameters.
S: Random number seed. (default 1)
D: If set, classifier is run in debug mode and may output additional info to the console
M: The minimal number of instances at the terminal nodes. (default 2)
N: The number of folds used in the minimal cost-complexity pruning. (default 5)
U: Don't use the minimal cost-complexity pruning. (default yes).
H: Don't use the heuristic method for binary split. (default true).
A: Use 1 SE rule to make pruning decision. (default no).
C: Percentage of training data size (0-1]. (default 1).
The Preliminary Attribute Check tests the underlying classifier against the DataTable specification at the inport of the node. Columns that are compatible with the classifier are marked with a green 'ok'. Columns which are potentially not compatible are assigned a red error message.
Important: If a column is marked as 'incompatible', it does not necessarily mean that the classifier cannot be executed! Sometimes, the error message 'Cannot handle String class' simply means that no nominal values are available (yet). This may change during execution of the predecessor nodes.
Capabilities: [Nominal attributes, Binary attributes, Unary attributes, Empty nominal attributes, Numeric attributes, Missing values, Nominal class, Binary class] Dependencies:  min # Instance: 1
It shows the command line options according to the current classifier configuration and mainly serves to support the node's configuration via flow variables.
