An issue with the naïve Bayes classifier is determining rare outcomes because the estimate is 0. To overcome this problem, the algorithm allows a replacement of zero probability with a nonzero value. This technique is called
A) replacement.
B) smoothing.
C) discrete.
D) combinations.

Smoothing techniques, such as Laplace smoothing, are used in naïve Bayes classifiers to handle the problem of zero probabilities for rare outcomes by assigning a small, nonzero probability to every outcome. This prevents the model from assigning a zero probability to an entire class or prediction.
