What is the primary purpose of the “Naive Bayes” algorithm in machine learning?

To perform text classification tasks based on conditional probabilities
To perform dimensionality reduction
To create regression models
To calculate p-values

The correct answer is A. To perform text classification tasks based on conditional probabilities.

Naive Bayes is a supervised machine learning algorithm that is used for classification tasks. It is based on Bayes’ theorem, which is a mathematical formula that calculates the probability of an event occurring given the occurrence of other events. Naive Bayes assumes that the features of a data set are independent of each other, which is why it is called “naive.” However, this assumption is often not true in real-world data sets. Despite this limitation, Naive Bayes is a simple and effective algorithm that is often used for text classification tasks.

Option B is incorrect because dimensionality reduction is a technique that is used to reduce the number of features in a data set. This can be done by finding a set of features that are highly correlated with the target variable.

Option C is incorrect because Naive Bayes is not used to create regression models. Regression models are used to predict continuous values, while Naive Bayes is used to predict discrete values.

Option D is incorrect because Naive Bayes is not used to calculate p-values. P-values are used to measure the statistical significance of a result.
