Bayes’ theorem. In addition, there are several types of Naïve Bayes algorithm, those are Gaussian, Multinomial and Bernoulli. In this project I will be using Multinomial Naïve Bayes since it’s the best one to be implemented in this text classification task due to its ability to maintain the number of word occurrences in each document.

Historical data and … Bayes' theorem is a formula that describes how to update the probabilities of hypotheses when given evidence. It follows simply from the axioms of conditional probability, but can be used to powerfully reason about a wide range of problems involving belief updates.

P(B|A) means the probability of happening B given the occurrence of A. P(A) and P(B) are the probability of happening A and B respectively. A textbook application of Bayes’s theorem is serology testing for Covid-19, which looks for the presence of antibodies to the virus. All tests are imperfect, and the accuracy of an antibody test Bayes’ theorem.

Naive Bayes uses the Bayes’ Theorem and assumes that all predictors are independent. In other words, this classifier assumes that the presence of one particular feature in a class doesn’t affect the presence of another one.

In section I there is 12 female and 18 male students. In section II there are 20 female and 15 male students. I bet you’ve also heard the famous formula: \(E = mc^2 \). That’s all there is to mass-energy equivalence. However, figuring out how to harness nuclear energy is still a hard problem. The formula made it possible, but implementing it still took 40 years. It’s the same with Bayes Theorem.
