Classification vs Regression

Classification Analytics Model

As the name suggests Classification analytics model identifies a class or a category among various categories. In clearer words, it identifies a class among a set of variables that are already established and the algorithm will be able to recognize the new variable and where it belongs.

Classification models are hugely used to make binary predictions and the algorithm predicts two options and which is likely to happen, but it will function only when examples are classified into two or more classes.

The different types of classification algorithms include

Decision Trees

Decision Trees are applicable in both classification and regression methods. It is built by building a decision tree where every node of the tree represents a test result and respective branches are possibles values of the attribute.

Random Forests

A Random Forest is a group of decision tree results that are increased into one final result. They can limit overfitting without increasing errors caused by bias; this makes them strong models. By training on different samples of data, Random Forests can reduce variance.

K-Nearest Neighbour

KNN algorithmMachine Learning is one of the uncomplicated ML algorithms based on the Supervised Learning Technique. It assumes the similarities between the new and available data and categorizes them based on pre-existing groups while storing all the available data. KNN incorporates a data point based on similarities of new and old data.

Regression Analytics Model

Regressions models are complex and predict the performance of a process, product, or professional. The Regression models will give a result of what will happen from an infinite number of possibilities.

The different types of Regression algorithms include:

Simple Linear Regression

With the help of simple linear regression, you can estimate the relationship between an independent and a dependent variable using a straight line if both variables are quantitative.

Multiple linear regression

It is an extension of simple linear regression, it can predict the value of dependent variables with the help of multiple independent variables.

Polynomial Regression

It is mainly used to find a nonlinear relationship between the independent ad dependent variables.

Classification VS Regression in Machine Learning

The important difference between regression and classification is while the former predicts continuous quality, the latter predicts discrete class labels. The classification can predict a continuous value in the form of class label probability, while regression predicts a discrete value in the form of an integer.
