Naive bayes algorithm program

Witryna1. Overview Naive Bayes is a very simple algorithm based on conditional probability and counting. Essentially, your model is a probability table that gets updated through your training data. To predict a new observation, you’d simply “lookup” the class probabilities in your “probability table” based on its feature values. It’s called “naive” because its … Witryna10 kwi 2024 · Naive Bayes classifiers are a family of “probabilistic classifiers” based on Bayes’ theorem with strong independence between the features. They are among the simplest Bayesian network models and are capable of achieving high accuracy levels. Bayes theorem states mathematically as:P(A B) = ( P(B A) * P(A) )/ P(B)where A and …
