How Naive Bayes Classifiers Work – with Python Code …

Notice we have the Name of each passenger. We won't use that feature for our classifier because it is not significant for our problem. We'll also get rid of the Fare feature because it is continuous and our features need to be discrete. There are Naive Bayes Classifiers that support continuous features. For example, the Gaussian Naive Bayes ...
