WebNov 4, 2024 · The Bayes Rule. 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. For observations in test or scoring data, the X would be known while Y is unknown. And for each row of the test dataset, you want to compute the ... WebJan 5, 2024 · The decision region of a Gaussian naive Bayes classifier. Image by the Author.
