Advantages Of Sampling Methods In Mining Pdf

Introduction to supervised methods 151 it is usually assumed that the training set tuples are generated randomly and independently according to some xed and unknown joint probability distribu-tion d over u.Note that this is a generalization of the deterministic case when a supervisor classies a tuple using a function y fx.
