A basic difference between K-NN classifier and Naive Bayes classifier is that the former is a discriminative classifier but the latter is a generative classifier. Going into specifics, K-NN classifier is a supervised lazy classifier which has local heuristics. Being a lazy classifier, it is difficult to use this for prediction in real time

Data pre-processing. Before feeding the data to the naive Bayes classifier model, we need to do some pre-processing.. Here, we’ll create the x and y variables by taking them from the dataset and using the train_test_split function of scikit-learn to split the data into training and test sets.. Note that the test size of 0.25 indicates we’ve used 25% of the data for testing

Dec 24, 2017 · Naive Bayes classifiers are among the most popular classifiers. While the assumption of class-conditional independence between variables is not true in general, naive Bayes classifiers have been found to work well in practice on many data sets. The fitcnb function can be used to create a more general type of naive Bayes classifier

>> Naive Bayes is a very simple model because it doesn't require setting any custom parameters. This method is referred to as naive because of the assumptions it makes about the data. The first assumption is independence between the predictors or features associated with each class and the second has to do with your validation sets
