Class RelativeRMSErrorFx

source code


Ratio between RMSE and root mean power of target output.

So it can be considered as a scaled RMSE -- perfect reconstruction has values near 0, while no reconstruction has values around 1.0. Word of caution -- it is not commutative, ie exchange of predicted and target might lead to completely different answers
