Which algorithms can be used for both regression and classification?

Some algorithms can be used for both classification and regression with small modifications, such as decision trees and artificial neural networks.

Can a classification problem be turned into a regression problem and vice versa?

For example, an intuitive regression problem can be reframed into a classification problem and vice versa.

Why can’t we use regression for classification problem?

There are two things that explain why Linear Regression is not suitable for classification. The first one is that Linear Regression deals with continuous values whereas classification problems mandate discrete values. The second problem is regarding the shift in threshold value when new data points are added.

Can we use regression for classification problems?

Whereas logistic regression is for classification problems, which predicts a probability range between 0 to 1. For example, predict whether a customer will make a purchase or not. The regression line is a sigmoid curve.

Can I use regression for classification?

What is the difference between regression and classification in data science?

But in reality, these two different approaches are complementary when going hand in hand to solve a data science problem. Most of the data science projects fall i nto two main categories — a regression problem (when the target variable is continuous/numerical) or classification problem (when the target variable (s) are discrete/categorical).

Can a regression problem be converted into a classification problem?

It’s worth noting that a regression problem can be converted into a classification problem by simply discretizing the response variable into buckets. For example, suppose we have a dataset that contains three variables: square footage, number of bathrooms, and selling price.

What is regression in statistics?

Regression A regression problem is when the output variable is a real or continuous value, such as “salary” or “weight”. Many different models can be used, the simplest is the linear regression. It tries to fit data with the best hyper-plane which goes through the points.

What is regregression in machine learning?

Regression is about finding an optimal function for identifying the data of continuous real values and make predictions of that quantity. Regression with multiple variables as input or features to train the algorithm is known as a multivariate regression problem.
