# Bank Note Dataset

## 1: Introduction

About this data

The Banknote Dataset involves predicting whether a given banknote is authentic given a number of measures taken from a photograph.

It is a binary (2-class) classification problem. The number of observations for each class is not balanced. There are 1,372 observations with 4 input variables and 1 output variable. The variable names are as follows:

1. Variance of Wavelet Transformed image (continuous).

2. Skewness of Wavelet Transformed image (continuous).

3. Kurtosis of Wavelet Transformed image (continuous).

4. Entropy of image (continuous).

5. Class (0 for authentic, 1 for inauthentic).
