Feature Ranking
===============

The feature weights are used for selecting and ranking
purposes inside one of the implemented schemes:

	* *Recursive Feature Elimination family* [Guyon02]_: RFE,
	  ERFE [Furlanello03]_, BISRFE, SQRTRFE 
	* *Recursive Forward Selection* family [Louw06]_: RFS
	* *One-step*
