What is Naive Bayes classifier model with example?
Working of Naïve Bayes' Classifier can be understood with the help of the below example: Suppose we have a dataset of weather conditions and corresponding target variable "Play". So using this dataset we need to decide that whether we should play or not on a particular day according to the weather conditions.
What is a real life example of Naive Bayes classifier?
Some best examples of the Naive Bayes Algorithm are sentimental analysis, classifying new articles, and spam filtration. Classification algorithms are used for categorizing new observations into predefined classes for the uninitiated data.
What is the example application of Naive Bayes?
Here are some applications of Naive Bayes algorithm:
As this algorithm is fast and efficient, you can use it to make real-time predictions.This algorithm is popular for multi-class predictions. Email services (like Gmail) use this algorithm to figure out whether an email is a spam or not.
The simple form of the calculation for Bayes Theorem is as follows: P(AB) = P(BA) * P(A) / P(B)
