Nettet20. mar. 2024 · How recursive feature elimination (RFE) works? In recursive feature elimination, we repeatedly train a model multiple times and each time we remove the least important feature from model determined by coef_ or feature_importance_ attribute of the model. We do this process until the model performance become worse. Nettet27. mar. 2024 · Recursive Feature Elimination (RFE) is a wrapper method that recursively eliminates features and builds a model over the remaining ones. It ranks the features based on importance and eliminates the least important ones until the desired number of features is reached.

Nettet11. nov. 2024 · 2 Answers. The reason it runs quickly when you remove "kernel='linear'", is because it fails quickly. Only SVR (kernel='linear') returns a coef_ that can be used by RFECV. If you use any other kernel, no coef_ is returned thus RFECV cannot work with it. By setting "step=1", you're forcing RFECV (SVR (kernel='linear'), step=1, … Nettet#risingfilmevaporator #RFE #RFEworking Friends in this lecture i have basically discussed about what is Rising film evaporator.
