Let the components of random vector x be conditionally independent given the class, and ternary valued (1, 0, or -1), with pij = P(xi = 1|wj), qij = P(xi = 0|wj) and rij = P(xi = -1|wj). Show (by deriving) that the Bayes classifier can be represented by quadratic discriminant functions.

When building a naïve Bayes classifier, we assume that the attributes are conditionally independent given the class label. The benefit of this assumption is: A. It makes it very simple to calculate the joint probabilities B. You can simply add probabilities for the individual attributes allowing for fast calculation C. The a priori probababilties for all possible outputs are the same D. The posteriori probabilities for all possible outputs are the same E. B & C
