Aug 19, 2020 · The Bayes Optimal Classifier is a probabilistic model that makes the most probable prediction for a new example. It is described using the Bayes Theorem that provides a principled way for calculating a conditional probability. It is also closely related to the Maximum a Posteriori: a probabilistic framework referred to as MAP that finds the most probable hypothesis for a training

    Apr 07, 2012 · The third edition of the "Data Mining" book mentions the User Classifier option on p. 424. However, I don't see it listed as a classifier under "trees" (or anywhere else, for that matter) in Weka 3.7.5. Has the option been removed? If so, what is the recommended way of doing the equivalent thing? By the way, I looked on the web and in the forums for "userclassifier" and "user classifier", but
