WebExample: {'sgd' 'lbfgs'} ... Small learning rates ensure convergence to the minimum, but can lead to slow termination. If Regularization is 'lasso', then experiment with various values of TruncationPeriod. For example, set TruncationPeriod to 1, 10, and then 100. For efficiency, the software does not standardize predictor data.
