Nave Bayes with Continuous (variables) Logistic Regression Machine Learning through Bayes rule But, can generate a sample of the data, P(X) Could use a Gaussian Nave Bayes classifier assume all X A Naive Bayes classifier considers each of these features (red, round, 3 in diameter) to contribute independently to the probability that the fruit is an apple, regardless of any correlations between features. Naive Bayes: Naive Bayes comes under supervising machine learning which used to make classifications of data sets.

It is used to predict things based on its prior knowledge and independence assumptions. This tutorial details Naive Bayes classifier algorithm, its principle, pros& cons, and provides an example using the Sklearn python Library. Context Lets take the famous Titanic Disaster dataset. To understand the naive Bayes classifier we need to understand the Bayes theorem. So lets first discuss the Bayes Theorem. How Naive Bayes classifier algorithm works in machine learning Click To Tweet.

What is Bayes Theorem? Bayes theorem named after Rev. Thomas Bayes. It works on conditional probability. The standard naive Bayes classifier (at least this implementation) assumes independence of the predictor variables, and Gaussian distribution (given the target class) of metric predictors. For attributes with missing values, the corresponding table entries are omitted for prediction. The Nave Bayes Classifier Direct application of Bayes theorem to compute the true probability of an event cannot, in general, be done.

However, the computation can be approximated, in many ways, and this leads to many practical classifiers and learning methods. One simple such method is called the Nave Bayes classifier.
