Which of the following is true about Naive Bayes?

Assumes that all the features in a dataset are equally important
Assumes that all the features in a dataset are independent
Both A and B
None of the above option

The correct answer is: C. Both A and B

Naive Bayes is a probabilistic machine learning algorithm that is used for classification and regression tasks. It is based on Bayes’ theorem, which is a mathematical formula that relates the probability of an event to the probability of other events that are known to be related to it.

Naive Bayes assumes that all the features in a dataset are independent. This means that the value of one feature does not affect the value of any other feature. This assumption is often not true in real-world data, but it can still be a useful approximation.

Naive Bayes also assumes that all the features in a dataset are equally important. This means that each feature contributes equally to the prediction of the target variable. This assumption is also often not true in real-world data, but it can still be a useful approximation.

Despite these assumptions, Naive Bayes can be a very effective machine learning algorithm. It is relatively simple to understand and implement, and it can be used to solve a variety of problems.

Here is a brief explanation of each option:

  • A. Assumes that all the features in a dataset are equally important

This is true for Naive Bayes. The algorithm assumes that each feature contributes equally to the prediction of the target variable. This assumption is often not true in real-world data, but it can still be a useful approximation.

  • B. Assumes that all the features in a dataset are independent

This is also true for Naive Bayes. The algorithm assumes that the value of one feature does not affect the value of any other feature. This assumption is often not true in real-world data, but it can still be a useful approximation.

  • C. Both A and B

This is the correct answer. Naive Bayes assumes that all the features in a dataset are equally important and independent.

  • D. None of the above option

This is not the correct answer. Naive Bayes does assume that all the features in a dataset are equally important and independent.
