Pseudocode for naive bayes classifier
Webnaïve Bayes classifier is based on, and it describes the algorithm for naïve Bayes classifier. Section 3 includes the design, development, and the testing of the classifier that was … WebNaïve Bayes classifier is a statistical classifiers, which predict class membership based on probabilities. Naive Bayes classifiers make use of class conditional independence, which makes it computationally faster. Class conditional independence means every attribute in the given class is independent of other attributes. Naive Bayes classifier ...
