Thomas Bayes was an 18th-century statistician and theologian known for his work in probability theory. He is best recognized for developing Bayes' theorem, which provides a mathematical framework for updating beliefs based on new evidence. This theorem has become a fundamental concept in statistics and is widely used in various fields, including science, finance, and artificial intelligence. Bayes was born in 1701 in London, England, and spent much of his life as a nonconformist minister. His work was published posthumously in 1763 by his friend Richard Price, who recognized the significance of Bayes' ideas. Today, Bayes' contributions continue to influence modern statistical methods and decision-making processes.
