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. Given a hypothesis

I. Example: A is event that suspect stole the $10, 000 under my mattress, B is event that suspect deposited several thousand dollars in cash in bank last week. Example: An internet search for "movie automatic shoe laces" brings up "Back to the future" Has the search engine watched the movie? No, but it knows from lots of other searches what people are probably looking for.. And it calculates that probability using Bayes' Theorem. Naive Bayes Explained. 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.

Further Information. The formula for Bayes' Theorem is as follows: Let's unpick the formula using our Covid-19 example. P(A|B) is the probability that a person has Covid-19 given that they have lost their sense of smell.

Bayes' formula is an important method for computing conditional probabilities. It is often used to compute posterior probabilities (as opposed to priorior probabilities) given observations. For example, a patient is observed to have a certain symptom, and Bayes' formula can be used to compute the probability that a diagnosis is 2016-01-04 Bayes' theorem, named after 18th-century British mathematician Thomas Bayes, is a mathematical formula for determining conditional probability.
