WebMay 7, 2024 · Naive Bayes are a family of powerful and easy-to-train classifiers, which determine the probability of an outcome, given a set of conditions using the Bayes’ theorem. In other words, the conditional probabilities are inverted so that the query can be expressed as a function of measurable quantities. Web1 day ago · Based on Bayes' theorem, the naive Bayes algorithm is a probabilistic classification technique. It is predicated on the idea that a feature's presence in a class is unrelated to the presence of other features. Applications for this technique include text categorization, sentiment analysis, spam filtering, and picture recognition, among many …
