Does classification for problems with nominal attributes (which it converts into binary attributes).
(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.
L: Use the baLanced version (default false)
I: The number of iterations to be performed. (default 1)
A: Promotion coefficient alpha. (default 2.0)
B: Demotion coefficient beta. (default 0.5)
H: Prediction threshold. (default -1.0 == number of attributes)
W: Starting weights. (default 2.0)
S: Default random seed. (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, Missing values, Binary class, Missing class values] Dependencies:  min # Instance: 0
It shows the command line options according to the current classifier configuration and mainly serves to support the node's configuration via flow variables.
