The Brains.VOS outputs can be used to quantify and track model accuracy. Depending on the model/application type some variables which can be tracked over time are:
Root Mean Square Error (RMSE)
Absolute Delta Between Predicted and Actual
Uncertainty (%)
etc..
This quantification is deployment type dependent. The example below shows a multi-line widget over time
Absolute Model Delta
Model Uncertainty
Models are updated to ensure the highest possible accuracy in the following situations:
Models are updated quarterly as a standard part of the subscription package
If the models uncertainty drifts outside of agreed boundaries
If there has been a change in configuration of the process itself (i.e. new pipe diameter)
