Hello all,
I have a doubt on Feature Selection. Actually, i am working on asthma patients dataset and I need to select the features that are actually making difference between the asthma patients and normal people. So, I have to do the feature selection and I am using filter techniques for feature selection. And, Finally, my doubt is how can we select the best k features from feature ranking. Can we use the grid search to know the k features???
Thanks in advance,
Dhanunjaya, Mitta
