The Bayes Rule is a way of going from P(X Y), known from the training dataset, to find P(Y X). To do this, we replace A and B in the above formula, with the feature X and response Y.

What is Bayes

WebBayes’ theorem converts the results from your test into the real probability of the event. For example, you can: Correct for measurement errors. If you know the real probabilities and the chance of a false positive and false negative, you can correct for measurement errors. Relate the actual probability to the measured test probability. WebAnd it calculates that probability using Bayes' Theorem. Bayes' Theorem is a way of finding a probability when we know certain other probabilities.

WebThe controversy arose when Bayes and contemporaries used the expression to solve the “inverse problem” to calculate the probability of cause: They let N represent an unknown state of nature and O represent observations about that state. In that way, the theorem starts with a personal subjective belief about the state of nature, Pr(N = n), and then, …
