The L_p regularizer for arbitrary integer p.
.hpp
Definition: add_to_po.hpp:21
static const int Power
The power of the regularizer.
The core includes that mlpack expects; standard C++ includes and Armadillo.
LRegularizer(double factor=1.0)
Create the regularizer object.
LRegularizer< 2 > L2Regularizer
The L2 Regularizer.
void serialize(Archive &ar, const unsigned int)
Serialize the regularizer (nothing to do).
LRegularizer< 1 > L1Regularizer
The L1 Regularizer.
void Evaluate(const MatType &weight, MatType &gradient)
Calculate the gradient for regularization.
double factor
The constant for the regularization.
