filter : informative variables , classification stage , relies on vaious measurment 

wrapper : more computation than filter , evaluation set within classification ,classifier dependant , better than filter.

embedded :is classifier dependent , in DT ,select as part of classifier design , combined space of feature subsets and classifier models .
