WebNaive Bayes is a supervised technique because it applies Bayes’ theorem. Supervised learning is a type of machine learning where the computer is “trained” on a set of known data, and then used to make predictions on new data. The training data is used to teach the computer how to recognize patterns and make predictions. female hare calledWebMar 22, 2024 · 1 Answer Sorted by: 3 The variant of Naive Bayes in unsupervised learning that I've seen is basically application of Gaussian Mixture Model (GMM, also known as … female harry potter and trunks fanfictionWebApr 1, 2024 · Naive Bayes methods are a set of supervised learning algorithms based on applying Bayes’ theorem with the “naive” assumption of conditional independence between every pair of features given the value of the class variable.
