In this blog post, I will first try to explain the basics of Lasso Regression. Then, we’ll build the model using a dataset with Python. Finally, we’ll evaluate the model by calculating the mean square error. Let’s get started step by step.
The main purpose in Lasso Regression is to find the coefficients that minimize the error sum of squares by applying a penalty to these coefficients. In another source, it is defined as follows:
_The “LASSO” stands for _L_east _A_bsolute _S_hrinkage and _S_election _Operator. Lasso regression is a regularization technique. It is used over regression methods for a more accurate prediction. This model uses shrinkage. Shrinkage is where data values are shrunk towards a central point as the mean. Lasso Regression uses L1 regularization technique. It is used when we have more number of features because it automatically performs feature selection.
