What is Classification in Data Mining?

Question

Can anyone explain the classification in Data Mining?

Answer 1

In Data mining, Classification is a process of finding a model that involves classifying the new observations based on observed patterns from the previous data. In short, if the target variable is discrete then it is a classification problem and if the target variable is continuous, it is a regression task.

The following are the most used classification algorithms in data mining:

• Logistic Regression
• Decision trees
• Random forest
• XG boost

Examples of classification in data mining include:

• Classification of emails as spam or not spam
• Classifying fraudulent and non-fraudulent transactions
