Naive Bayes (ML_CN_5)

This function uses the Bayes' theorem to calculate the probability of each class based on the frequency of the features in the training data, and classifies new input data based on highest probability

Naive Bayes is a probabilistic machine learning algorithm that uses Bayes' theorem to make predictions. It assumes that the features are independent of each other and calculates the probability of each class based on the frequency of the features in the training data.

Once the probabilities of each class are calculated, new input data is classified based on the class with the highest probability.
