Neural net classifiers are studied in artificial intelligence and are not covered here
Bayesian classifiers use Bayes’ theorem, which says p(cj | d) = p(d | cj) * p(cj) / p(d)wherep(cj | d) = probability of instance d being in class cj, p(d | cj) = probability of generating instance d given class cj p(cj) = probability of occurrence of class cj, and p(d) = probability of instance d occurring
