WebNaive Bayes is a supervised machine learning algorithm used for classification. It uses the Bayes theorem of probability to calculate the probability of an event occurring. It assumes that the features of the data are independent of each other, which makes the algorithm faster and more efficient. WebNaive Bayes models are a group of extremely fast and simple classification algorithms that are often suitable for very high-dimensional datasets. Because they are so fast and have so few tunable parameters, they end up being very useful as a quick-and-dirty baseline for a classification problem. This section will focus on an intuitive ...
