Predicting the authenticity of banknotes

In this section, we will study the problem of predicting whether a particular banknote is genuine or whether it has been forged. The banknote authentication data set is hosted at The creators of the data set have taken specimens of both genuine and forged banknotes and photographed them with an industrial camera.

Three features of this transform are constructed, and along with the image entropy, they make up the four features in total for this binary classification task.
