What is classification?

Programming Language
1

A predictive modelling method in which a class label is anticipated for a given example of input data is referred to as classification. It aids in categorizing the supplied data into a label that is shared by other observations with comparable characteristics. It can, for example, be used to identify a message as spam or to determine whether or not a user would churn based on their behavior.

Some of the classification algorithms used in Machine Learning are as follows:

  • Decision tree
  • Random forest classifier
  • Support vector machine

Classification is the process of given previously unknown sample, decide to which group it belongs.

Example: imagine you have to guess the age of a person based on the person looks. You already have an idea of how each age should look like, and you classify it into a group of people of age X.
