 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The classification of spam mail and normal mail falls under ____ category.
 A Binary Logistic Regression B Multinomial Logistic Regression C Ordinal Logistic Regression D Linear Regression
Explanation:

Detailed explanation-1: -Logistic regression is an approach for demonstrating the relationship between a binary dependent variable, and several explanatory variables. With the dependent variable being binary, it can only take on two values, which in this case is ”Spam”, or ”No Spam”.

Detailed explanation-2: -Logistic regression is one of the most likely and appropriate algorithm used for classification of datasets. In case of classifying a dataset named as spam base the logistic regression is the most versatile decision based approach for detecting spam emails out of a dataset.

Detailed explanation-3: -With Bayes’ Rule, we want to find the probability an email is spam, given it contains certain words. We do this by finding the probability that each word in the email is spam, and then multiply these probabilities together to get the overall email spam metric to be used in classification.

Detailed explanation-4: -The methodology is used for the process of e-mail spam filtering based on Naıve Bayes algorithm. 3.1. Naıve Bayes classifier The Naıve Bayes algorithm is a simple probabilistic classifier that calculates a set of probabilities by counting the frequency and combination of values in a given dataset .
