Pros and cons of naive bayes
Webb9 apr. 2024 · Let’s find why. The Naive Bayes classifier is based on finding functions describing the probability of belonging to a class given features. We write it P ( Survival f1,…, fn). We apply the Bayes law to simplify the calculation: Formula 1: Bayes Law P ( Survival) is easy to compute and we do not need P ( f1,…, fn) to build a classifier. Webb30 apr. 2024 · Smoothing: Naive Bayes can suffer from zero-frequency problems when a particular feature and class combination is not present in the training data. Smoothing techniques such as Laplace smoothing and Additive smoothing can help address this problem by adding a small constant to the count of each feature.
