public class LogisticRegressionWithSGD
extends GeneralizedLinearAlgorithm<LogisticRegressionModel>
implements Serializable
Train a classification model for Binary Logistic Regression
using Stochastic Gradient Descent. By default L2 regularization is used,
which can be changed via
LogisticRegressionWithSGD.optimizer
.
Using LogisticRegressionWithLBFGS
is recommended over this.

- Note:
- Labels used in Logistic Regression should be {0, 1, ..., k - 1} for k classes multi-label classification problem.
