WebBayes' theorem is a formula that describes how to update the probabilities of hypotheses when given evidence. It follows simply from the axioms of conditional … WebFeb 19, 2024 · Bayes’s formula provides relationship between P (A B) and P (B A) · Naive Bayes A Naive Bayes algorithm assumes that each of the features it uses are conditionally independent of one another given some class. It provides a way of calculating posterior probability P (c x) from P (c), P (x) and P (x c).
Bayes
Bayes' theorem is stated mathematically as the following equation: where $${\displaystyle A}$$ and $${\displaystyle B}$$ are events and $${\displaystyle P(B)\neq 0}$$. $${\displaystyle P(A\mid B)}$$ is a conditional probability: the probability of event $${\displaystyle A}$$ occurring given that … See more In probability theory and statistics, Bayes' theorem (alternatively Bayes' law or Bayes' rule), named after Thomas Bayes, describes the probability of an event, based on prior knowledge of conditions that might be related to the … See more Bayes' theorem is named after the Reverend Thomas Bayes (/beɪz/), also a statistician and philosopher.
