what are different types of regression models available . - manjunath - 12-23-2022
Regression models are a type of machine learning model that are used to predict a continuous output value based on one or more input features. There are many different types of regression models, each with its own strengths and weaknesses. Here are some common types of regression models:
1) Linear regression: This is a simple regression model that assumes a linear relationship between the input features and the output. It is used to predict a continuous output value based on a single input feature or a linear combination of input features.
2) Logistic regression: This is a regression model that is used to predict a binary outcome (such as yes/no or 0/1) based on one or more input features. It is used in classification tasks and is based on the logistic function, which maps the input features to a probability between 0 and 1.
3) Polynomial regression: This is a regression model that is used to fit a non-linear relationship between the input features and the output. It is based on a polynomial function and can be used to fit higher-order relationships in the data.
4) Ridge regression: This is a regularized version of linear regression that is used to prevent overfitting. It adds a penalty term to the loss function to constrain the size of the coefficients and reduce the complexity of the model.
5) Lasso regression: This is another regularized version of linear regression that is used to prevent overfitting. It adds a penalty term to the loss function to constrain the size of the coefficients and reduce the complexity of the model.
6) Elastic Net: This is a combination of ridge and lasso regression that combines the penalties of both models. It is used to balance the trade-off between the simplicity of the model and the fit of the model to the data
