Interface DifferentiableRegularization<T>

Type Parameters:

T - The type of the coefficients being regularized.

All Superinterfaces:

breeze.optimize.DiffFunction<T>, scala.Function1<T,Object>, breeze.linalg.ImmutableNumericOps<breeze.optimize.StochasticDiffFunction<T>>, breeze.linalg.NumericOps<breeze.optimize.StochasticDiffFunction<T>>, breeze.optimize.StochasticDiffFunction<T>

public interface DifferentiableRegularization<T>
extends breeze.optimize.DiffFunction<T>

A Breeze diff function which represents a cost function for differentiable regularization of parameters. e.g. L2 regularization: 1 / 2 regParam * beta dot beta
