Class LinearRegressionTrainingSummary

java.lang.Object

org.apache.spark.ml.regression.LinearRegressionSummary

org.apache.spark.ml.regression.LinearRegressionTrainingSummary

All Implemented Interfaces:

java.io.Serializable

public class LinearRegressionTrainingSummary
extends LinearRegressionSummary

:: Experimental :: Linear regression training results. Currently, the training summary ignores the training weights except for the objective trace.

param: predictions predictions output by the model's transform method. param: objectiveHistory objective function (scaled loss + regularization) at each iteration.
