Naive Bayes ist eine statistische Klassifizierungstechnik, die auf dem Bayes-Theorem basiert. Er ist einer der einfachsten überwachten Lernalgorithmen. Der Naive Bayes-Klassifikator ist ein schneller, genauer und zuverlässiger Algorithmus. Naive Bayes-Klassifikatoren haben eine hohe Genauigkeit...
Bayes’ theorem forms the core of the whole concept of naive Bayes classification. Theposterior probability, in the context of a classification problem, can be interpreted as: “What is the probability that a particular object belongs to classiigiven its observed feature values?” A more concrete...

By Bayes' Theorem, we have that P(C_j|D) = P(D|C_j)*P(C_j)/P(D). The LHS is the probability that the document belongs to class C_j given the document itself (by which is meant, in practice, the word frequencies occurring in this document), and our program will calculate thi...

As shown in Figure 1, developing a Naive Bayes classifier considers Bayes’ theorem with conditional independence assumption between every pair of variables: Pr(𝐶𝑖|𝐗𝑗)=Pr(𝐗𝑗|𝐶𝑖)Pr(𝐶𝑖)Pr(𝐗𝑗)PrCi|Xj=PrXj|CiPrCiPrXj (1) in which 𝑖,𝑗=1,2…,𝑁i,j=...

BO is essentially a Bayesian approach based on Bayes' theorem. The purpose of Bayesian approaches is to use the information obtained from the data as prior information and to reveal how the existing information will be updated with the obtained posterior information [36, 37]. Using the Bayesian...
