A small-sample correction, or pseudo-count, will be incorporated in every probability estimate. 2. Consequently, no probability will be zero. 3. This is a way of regularizing Naive Bayes, and when the pseudo-count is zero, it is called Laplace smoothing. 4. While in the general case it is often called Lidstone smoothing.
