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 dataset is hosted at https://archive.ics.uci.edu/ml/datasets/banknote+authentication. The creators of the dataset have taken specimens of both genuine and forged banknotes and photographed them with an industrial camera. The resulting grayscale image was processed using a type of time-frequency transformation known as a wavelet transform. 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.

Column name	Type	Definition
waveletVar	Numerical	Variance of the wavelet-transformed image
waveletSkew	Numerical	Skewness of the wavelet-transformed image
waveletCurt	Numerical	Kurtosis of the wavelet-transformed image
entropy	Numerical	Entropy of the image
class	Binary	Authenticity...
