The Naive Bayes algorithm is a probabilistic machine learning model that's used for classification problems. It's a type of linear "probabilistic classifier" that assumes features are conditionally independent, given the target class.  The Naive Bayes algorithm is easy to build and is often used for large datasets. It can be used for both binary and multi-class classification problems.  Here are some requirements for a Naive Bayes model: A single key column Input columns that are either discrete, or the values have been binned  The Naive Bayes algorithm is often used in sentiment...
