All weka dialogs have a panel where you can specify classifier-specific parameters.
D: Show Debugging Output
P: Distribution of the Prior (1=Gaussian, 2=Laplacian) (default: 1=Gaussian)
H: Hyperparameter Selection Method (1=Norm-based, 2=CV-based, 3=specific value) (default: 1=Norm-based)
V: Specified Hyperparameter Value (use in conjunction with -H 3) (default: 0.27)
R: Hyperparameter Range (use in conjunction with -H 2) (format: R:start-end,multiplier OR L:val(1), val(2), ..., val(n)) (default: R:0.01-316,3.16)
Tl: Tolerance Value (default: 0.0005)
S: Threshold Value (default: 0.5)
F: Number Of Folds (use in conjuction with -H 2) (default: 2)
I: Max Number of Iterations (default: 100)
N: Normalize the data
seed: Seed for randomizing instances order in CV-based hyperparameter selection (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: [Binary attributes, Unary attributes, Empty nominal attributes, Numeric attributes, Binary class] 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.
