Bayes’ Theorem and Naive Bayes Classifier Definition. Bayes’ Theorem is a powerful tool that enables us to calculate posterior probability based on given prior knowledge and evidence. It’s the same principle as doing a training on data and obtaining useful knowledge for further prediction.
Naive Bayes Algorithm: Theory, Assumptions
Abstractly, naive Bayes is a conditional probability model: it assigns probabilities for each of the K possible outcomes or classes given a problem instance to be classified, represented by a vector encoding some n features (independent variables). The problem with the above formulation is that if the number of features n is la… atta ka rate

In machine learning, a Bayes classifier is a simple probabilistic classifier, which is based on applying Bayes' theorem. The feature model used by a naive Bayes classifier makes strong independence assumptions. This means that the existence of a particular feature of a class is independent or unrelated to the existence of every ...
