Java Applet

This applet allows for the calculation of the decision boundary given a three dimensional feature vector. Specifically, by stipulating the variables such as the priors, and the conditional likelihoods of each feature with respect to each class, the changing decision boundary will be displayed.

How to use the Applet

Use the scroll bars to input the values of P and Q where they are the probabilities of X=1 given class 1 or class 2 respectively. Furthermore, the Pw1 and Pw2 are the respected priors. once complete, press the compute button and the decision plane will be displayed given that it exists and is not infinity.
