question: public static int [ ] createBootstrappingMapping ( ExampleSet exampleSet , int size , Random random ) { int [ ] mapping = new int [ size ] ; for ( int i = 0 ; i < mapping . length ; i ++ ) { mapping [ i ] = random . nextInt ( exampleSet . size ( ) ) ; } return mapping ; }
target:  Creates a new mapping for the given example set by sampling with replacement.
