Given a continuous data vector 'z', classify it returning the class number (0, ..., k-1) with the highest relative posterior probability.
Given a continuous data vector 'z', classify it returning the class number (0, ..., k-1) with the highest relative posterior probability. The vector 'z' id first converted to an integer valued vector by rounding.

The
BayesNetworkclass implements a Bayesian Network Classifier. It classifies a data vector 'z' by determining which of 'k' classes has the highest Joint Probability of 'z' and the outcome (i.e., one of the 'k' classes) of occurring. The Joint Probability calculation is factored into multiple calculations of Conditional Probability. Conditional dependencies are specified using a Directed Acyclic Graph (DAG). Nodes are conditionally dependent on their parents only. Conditional probability are recorded in tables. Training is achieved by ...
