[All Databricks Certified Professional Data Scientist Questions]

A fruit may be considered to be an apple if it is red, round, and about 3" in diameter. A naive Bayes classifier considers each of these features to contribute independently to the probability that this fruit is an apple, regardless of the

APresence of the other features.

BAbsence of the other features.

CPresence or absence of the other features

DNone of the above
In simple terms, a naive Bayes classifier assumes that the value of a particular feature is unrelated to the presence or absence of any other feature, given the class variable. For example, a fruit may be considered to be an apple if it is red, round, and about 3' in diameter A naive Bayes classifier considers each of these features to contribute independently to the probability that this fruit is an apple, regardless of the presence or absence of the other features.

Wait, so the classifier doesn't even consider if the fruit has a worm in it? That's some serious fruit discrimination if you ask me!

User 2: Yeah, the classifier assumes each feature contributes independently to the probability of the fruit being an apple.

User 1: It doesn't matter if the fruit has a worm, the classifier only looks at specific features.

Hmm, I was a bit unsure about this one. But now it makes sense - the classifier doesn't care if the apple is also juicy or has a stem, as long as it's red, round, and 3 inches wide.

Ah, I see! So, it's like saying the fruit's color doesn't depend on whether it's round or not. That's a pretty neat assumption for a classifier to make.

But wouldn't the presence or absence of other features affect the probability of the fruit being an apple?

The correct answer is C) Presence or absence of the other features. A naive Bayes classifier assumes that each feature contributes independently to the probability of the class variable, regardless of the presence or absence of the other features.
