Bayes' theorem lets us use this information to compute the "direct" probability of J.
The general Bayesian classifier is a kind of classification algorithm that is based on Bayes' theorem. The naive Bayes (NB) algorithm is a very simple, straightforward classification algorithm .
Thoughtful assessment (e.g., calculation of Bayes' theorem statistics) may verify or challenge initial quick impressions but can be difficult to achieve in fast-paced clinical care settings.
The chapter on probabilistic reasoning starts off well with a brief but informative discussion of Bayes' theorem, but does not pursue this very interesting subject or bring out its more curious aspects.
