WebFeb 24, 2024 · Forward selection – This method is an iterative approach where we initially start with an empty set of features and keep adding a feature which best improves our model after each iteration. The stopping criterion is till the addition of a new variable does not improve the performance of the model. WebFeb 16, 2024 · Stepwise elimination is a hybrid of forward and backward elimination and starts similarly to the forward elimination method, e.g. with no regressors. Features are then selected as described in forward feature selection, but after each step, regressors are checked for elimination as per backward elimination. gives a hand nyt
