Abstract:

The goal of classifier model training is not to learn an exact representation of the training
data itself, but rather to build a statistical model of the process which generates the data.
This is important if the classifier is to exhibit good generalization, that is, to make good
predictions for new inputs. Using the simple analogy of curve fitting using polynomials, we
should that a polynomial with too few coefficients gives poor predictions for new data, ie
poor generalization, since the polynomial function has too little flexibility.
