LogoutRegularization is one of the most important concepts of machine learning. It is a technique to prevent the model from overfitting by adding extra information to it.
Sometimes the machine learning model performs well with the training data but does not perform well with the test data. It means the model is not able to predict the output when deals with unseen data by introducing noise in the output, and hence the model is called overfitted. This problem can be deal with the help of a regularization technique.
This technique can be used in such a way that it will allow to maintain all variables or features in the model by reducing the magnitude of the variables. Hence, it maintains accuracy as well as a generalization of the model.
It mainly regularizes or reduces the coefficient of features toward zero. In simple words, " In regularization technique, we reduce the magnitude of the features by keeping the same number of features."
