question: public static double [ ] normalise ( double [ ] initProbs ) { for ( int i = 0 ; i < initProbs . length ; i ++ ) { if ( initProbs [ i ] < 0 ) { initProbs [ i ] = 0.0 ; } } double sum = 0.0 ; for ( double prob : initProbs ) { sum += prob ; } double [ ] result = new double [ initProbs . length ] ; if ( sum > 0.001 ) { for ( int i = 0 ; i < initProbs . length ; i ++ ) { result [ i ] = initProbs [ i ] / sum ; } } else { for ( int i = 0 ; i < initProbs . length ; i ++ ) { result [ i ] = 1.0 / initProbs . length ; } } return result ; }
target:  Normalises the double array (ensuring that the sum is equal to 1.0).
