Learn how to implement the NB Classifier or bayesian classification in R and Python with a sample project. If you prefer to learn the Naive Bayes’ theorem from the basics concepts to the implementation in a structured manner, you can enroll in this free course: Naive Bayes Course from Scratc...
The Naive Bayes Classifier assumes that the presence of a particular feature is unrelated to the presence of any other feature. It’s based on the Bayes’ Theorem, which assumes the independence of predictors. For example, a fruit is considered Orange if it’s round, orange in color and 4...
