• ### how naive bayes classifiers work – with python code examples

Naive Bayes Classifiers (NBC) are simple yet powerful Machine Learning algorithms. They are based on conditional probability and Bayes's Theorem. In this post, I explain "the trick" behind NBC and I'll give you an example that we can use to solve a classification problem. In the next sections, I'll be talking about the math behind NBC

Jun 18, 2020 · Naive Bayes is a probabilistic classifier that allows us to do this. Based on a few sample values, the Naive Bayes classifier understands what the rules are and can classify a new test case when presented with one. Now, each value that enters a sample initially comes from a probability distribution that the population follows. So our job now is

Feb 14, 2020 · Naive Bayes is a supervised learning algorithm used for classification tasks. Hence, it is also called Naive Bayes Classifier. As other supervised learning algorithms, naive bayes uses features to make a prediction on a target variable

• ### a practical explanation of anaive bayes classifier

The simplest solutions are usually the most powerful ones, and Naive Bayes is a good example of that. In spite of the great advances of machine learning in the last years, it has proven to not only be simple but also fast, accurate, and reliable. It has been successfully used for many purposes, but it works particularly well with natural language processing (NLP) problems

1.9.4. Bernoulli Naive Bayes¶. BernoulliNB implements the naive Bayes training and classification algorithms for data that is distributed according to multivariate Bernoulli distributions; i.e., there may be multiple features but each one is assumed to be a binary-valued (Bernoulli, boolean) variable. Therefore, this class requires samples to be represented as binary-valued feature vectors
