Package org.elasticsearch.client.ml.dataframe.evaluation.regression

Class MeanSquaredLogarithmicErrorMetric

java.lang.Object
org.elasticsearch.client.ml.dataframe.evaluation.regression.MeanSquaredLogarithmicErrorMetric
All Implemented Interfaces:
EvaluationMetric, org.elasticsearch.common.xcontent.ToXContent, org.elasticsearch.common.xcontent.ToXContentObject
public class MeanSquaredLogarithmicErrorMetric
extends java.lang.Object
implements EvaluationMetric
Calculates the mean squared error between two known numerical fields. equation: msle = 1/n * Σ(log(y + offset) - log(y´ + offset))^2 where offset is used to make sure the argument to log function is always positive
