WebBased on all these, the objective of the research is to exploit the efficacy of the hybridized model using an ensemble approach in heart disease prediction. The aim of this study is to develop a smart heart disease prediction system, which is applicable in terms of accuracy, reliability and practical utility. WebBayes’s Theorem Bayes’s theorem (written “Bayes’ theorem” by some and named after the 18th-century cler-gyman and mathematician Thomas Bayes) is the formula for deriving the posterior distribution. In the form used in Bayesian statistics, the theorem can be simply expressed as f( θ x)∝. (6.1) To understand this formula, ﬁrst note ...

In estimation theory and decision theory, a Bayes estimator or a Bayes action is an estimator or decision rule that minimizes the posterior expected value of a loss function (i.e., the posterior expected loss). Equivalently, it maximizes the posterior expectation of a utility function. An alternative way of formulating an estimator within Bayesian statistics is maximum a posteriori estimation.
