that fits exactly to existing (DOE) data points. In Encore, the example of this is Kriging. However, a function that fits your data exactly may not be a good predictive model of your phenomenon. Such a transfer function may yield very poor predictions of data points that are between (amidst) your data, or...

In practice, a certain segment of data will be labelled with these classifications. The machine learner's task is...
