Object
org.apache.spark.mllib.regression.GeneralizedLinearAlgorithm<LogisticRegressionModel>
org.apache.spark.mllib.classification.LogisticRegressionWithSGD
All Implemented Interfaces:
Serializable, org.apache.spark.internal.Logging
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.
