In this post, we are going to implement theNaive Bayes classifierin Python using my favorite machine learning library scikit-learn. Next, we are going to use the trained Naive Bayes (supervised classification), model to predict the Census Income. As we discussed the Bayes theorem innaive Bayes...
The multinomial Naive Bayes classifier is suitable for classification with discrete features such as word counts for text classification. It requires integer feature counts such as bag-of-words or tf-idf feature extraction applied to text. For this example, I will use the dataset called “Twenty ...
