Naive Bayes Classifier Full Bayes Classifier

Each color is associated with a class: red - iris setosa, green - iris versicolor, blue - iris virginica. The intensity of the color is the conditional probability density. The left screenshot shows the naive Bayes classifier, the right one the full Bayes classifier. The ellipses are the 2sigma-boundaries of the probability density functions (compare Figure 6.2, Section 6.1.3, page 156).

These screenshots were generated from the induced classifiers with the Bayes classifier visualization program listed here.
