🤖 AI for Naive Bayes

📘 Definition

AI for Naive Bayes involves the use of the Naive Bayes algorithm, a probabilistic machine learning model based on Bayes’ theorem, used for classification tasks assuming feature independence.

🔍 Detailed Description

Naive Bayes is a simple yet effective classification algorithm in artificial intelligence that applies Bayes’ theorem with the "naive" assumption that all features are independent of each other. Despite this assumption, it performs well in many real-world applications, especially in text classification and spam filtering.

The algorithm calculates the posterior probability for a class given a set of features and selects the class with the highest probability. It requires relatively small amounts of training data and is fast and efficient, making it suitable for large-scale data tasks.

Naive Bayes comes in several variants such as Gaussian, Multinomial, and Bernoulli, each suited for different types of data like continuous, discrete, or binary features. Its simplicity allows for easy implementation and scalability.
