WebMay 11, 2024 · A good paper to read on this is "Bayesian Network Classifiers, Machine Learning, 29, 131–163 (1997)". Of particular interest is section 3. Though Naive Bayes is a constrained form of a more general Bayesian network, this paper also talks about why Naive Bayes can and does outperform a general Bayesian network in classification tasks. WebJul 4, 2024 · Bayes’ Theorem is named after Thomas Bayes. He first makes use of conditional probability to provide an algorithm which uses evidence to calculate limits on an unknown parameter. Bayes’ Theorem has two types of probabilities : Prior Probability [P (H)] Posterior Probability [P (H/X)] Where, X – X is a data tuple. H – H is some Hypothesis. karl marx the communist manifesto
