Gets information about ridge regression process used for sensor identification
Contents
Method of virtualsensor object.
Syntax
info = getIdentificationInformation(object)
info is a structure with the following fields:
- wnorm: it is the 2 norm of the weights vector w (for 0 order Tikhonov regularization) or the 2 norm of L w (for 1 order Tikhonov regularization)
- residual: it is the 2 norm of the residual
( i.e. 
)
- test_error: it is the 2 norm of the residual computed in the test set (if provided), i.e.
.
see function ridgeRegression for further details.
