Backpropagation Neural Network Error
SAP HANA provides a Backpropagation Neural Network in the Predictive Analytics Library in SP09.
Each of the trained algorithm returns an error. But we are not told how this error is derived.
Please I will like to know if this error is calculated using the Root Mean Square Error (which is the standard) or something else is used to arrive at this error.
Any assistance will be greatly appreciated.
