How can i make feature selection in ensemble class?

I need help in making feature selection in the result I got from merging two features. does a selection technique mean removing the zeros numbers from the result file and does it possibly make the result better ? I used the ensemble class for concatenation … is there any example for feature selection or how can I find one ?

is there any help please ?

For general feature selection approaches, take a look at sklearn’s feature selection. While these techniques are mostly targeting the input features, they might still be useful in case you want to adapt them to your use case. I don’t know any standard approach in selecting features from different models before concatenating them, but someone else might :wink:
