WebSep 25, 2024 · So, Bayes’ Rule represents the probability of an event based on the prior knowledge of the conditions that might be related to that event, as Analytics Vidhya accurately states. If we already know the conditional probability, we use Bayes’ Theorem to find the reverse probabilities. WebIn 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 …

WebThis process, of using Bayes’ rule to update a probability based on an event affecting it, is called Bayes’ updating. More generally, the what one tries to update can be considered ‘prior’ information, sometimes simply called the prior. The event providing information about this can also be data.
