WebMar 1, 2024 · Abstract. A naïve Bayes approach to theory confirmation is used to compute the posterior probabilities for a series of four models of DNA considered by James Watson and Francis Crick in the early 1950s using multiple forms of evidence considered relevant at the time. Conditional probabilities for the evidence given each model are estimated from … WebMay 18, 2024 · Now, decision theory in Machine Learning is the strategies and method involved in choosing a particular action among a number of probable actions. 3.
