- All Implemented Interfaces:
EvaluationMetric
,org.elasticsearch.xcontent.ToXContent
,org.elasticsearch.xcontent.ToXContentObject
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
