naive bayes classifier using gaussian probability

Sep 05, 2020 · Although Bayes Theorem — put simply, is a principled way of calculating a cond i tional probability without the joint probability — assumes each input is dependent upon all other variables, to use it as a classifier we remove this assumption and consider each variable to be independent of each other and refer to this simplification of Bayes Theorem for predictive modelling as the Naive Bayes …

    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

    In this article, we have learned how the Gaussian naive Bayes classifier works and gave an intuition on why it was designed that way — it is a direct approach to model the probability of interest. Compare this with Logistic regression: there, the probability is modeled using a linear function with a sigmoid function applied on top of it
