The base classifiers are "graded".

(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.
M: Full name of meta classifier, followed by options. (default: "weka.classifiers.rules.Zero")
X: Sets the number of cross-validation folds.
S: Random number seed. (default 1)
num-slots: Number of execution slots. (default 1 - i.e. no parallelism)
B: Full class name of classifier to include, followed by scheme options. May be specified multiple times. (default: "weka.classifiers.rules.ZeroR")
D: If set, classifier is run in debug mode and may output additional info to the console
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.

It shows the command line options according to the current classifier configuration and mainly serves to support the node's configuration via flow variables.
