class BayesClfML extends Classifier
The BayesClfML class implements an Integer-Based Naive Bayes Multi-Label Classifier, which is a commonly used such classifier for discrete input data.
The BayesClfML class implements an Integer-Based Naive Bayes Multi-Label Classifier, which is a commonly used such classifier for discrete input data. The classifier is trained using a data matrix 'x' and a classification matrix 'y'. Each data vector in the matrix is classified into one of 'k' classes numbered 0, ..., k-1. Prior probabilities are calculated based on the population of each class in the training-set. Relative posterior probabilities are computed by multiplying these by values computed using conditional probabilities. The classifier is naive, because it assumes feature independence and therefore simply multiplies the conditional probabilities.
