Class RidgeReg

source code

Ridge regression Classifier.

This ridge regression adds an intercept term so your labels do not have to be zero-centered.

Overrides: object.__init__

__repr__(self)
(Representation operator)

source code 
String summary of the object
Parameters:

  • prefixes - What other prefixes to prepend to list of arguments
Overrides: object.__repr__

_train(self, data)

source code 
Train the classifier using data (Dataset).
Overrides: base.Classifier._train

_predict(self, data)

source code 
Predict the output for the provided data.
Overrides: base.Classifier._predict
