Naive Bayes Classification

Load Data Set

Task: Load the banknotes data set (cf. Detecting Forgery with k-NN). Drop the entropy column.

Naive Bayes

Task: Use Scikit-Learns’s GaussianNB to create a model for banknote authentication.

Solution:

# your solution

Decision Surface and Distributions

Task: Train a second model which only uses variance and skewness. Plot the training data set and the decision curve as well as the two Gaussian densities estimated from the training samples by the naive Bayes classifier.

Solution:
