True or False: In a naive Bayes algorithm, the entire posterior probability will be zero when an attribute value in the testing record has no example in the training set.
A. True
B. False
C. Can’t be determined
D. None of these
Answer:A
True or False: In a naive Bayes algorithm, the entire posterior probability will be zero when an attribute value in the testing record has no example in the training set.
A. True B. False C. Can’t be determined D. None of these
Explanation: Since for a particular value in the attribute, the probability will be zero due to the absence of an example present in the training dataset. This usually leads to the problem of zero probability in the Naive Bayes algorithm. For further reference, refer to the given article Link.
