public class RidgeRegressionWithSGD
extends GeneralizedLinearAlgorithm<RidgeRegressionModel>
implements scala.Serializable
Train a regression model with L2-regularization using Stochastic Gradient Descent.
This solves the l2-regularized least squares regression formulation
f(weights) = 1/2n ||A weights-y||^2^ + regParam/2 ||weights||^2^
Here the data matrix has n rows, and the input RDD holds the set of rows of A, each with
its corresponding right hand side label y.
See also the documentation for the precise formulation.
