Improving naive bayes algorithm
WitrynaNaïve Bayes Classifier is one of the simple and most effective Classification algorithms which helps in building the fast machine learning models that can make quick predictions. It is a probabilistic classifier, which means it predicts on the basis of … Witryna31 mar 2024 · The Naive Bayes algorithm assumes that all the features are independent of each other or in other words all the features are unrelated. With that assumption, we can further simplify the above formula and write it in this form. This is the final equation of the Naive Bayes and we have to calculate the probability of both C1 …
