system
suppose you have a dataset with 30 attributes. select the feature selection method you will use to select the best subset of attributes.
user
a suitable feature selection method to select a subset of attributes from a dataset with 30 attributes would be a wrapper method, such as recursive feature elimination (rfe) or sequential feature selection (sfs). in rfe, a subset of attributes are selected and evaluated by a predictive model. the subset of attributes with the highest model accuracy are retained and used for predicting. in sfs, a subset of features are selected by evaluating each attribute's contribution to the model accuracy and adding the most important attribute each time to the current subset.
