Train a Lasso model given an RDD of (label, features) pairs.
Train a Lasso model given an RDD of (label, features) pairs. We run a fixed number of iterations of gradient descent using a step size of 1.0. We use the entire data set to update the gradient in each iteration.
RDD of (label, array of features) pairs.
Number of iterations of gradient descent to run.

Train a Lasso model given an RDD of (label, features) pairs.
Train a Lasso model given an RDD of (label, features) pairs. We run a fixed number
of iterations of gradient descent using the specified step size. Each iteration uses
miniBatchFraction
fraction of the data to calculate the gradient.

Train a Lasso model given an RDD of (label, features) pairs. We run a fixed number
of iterations of gradient descent using the specified step size. Each iteration uses
miniBatchFraction
fraction of the data to calculate the gradient. The weights used in
gradient descent are initialized using the initial weights provided.
