. ▁ ▁It ▁is ▁clear ▁from ▁Fig . ▁ 3 ▁that ▁there ▁can ▁be ▁two ▁outputs ▁to ▁an ▁interval ▁type - 2 ▁F LS — c ris p ▁numerical ▁values ▁and ▁the ▁type - redu ced ▁set . ▁The ▁latter ▁provides ▁a ▁measure ▁of ▁the ▁un cert aint ies ▁that ▁have ▁flow ed ▁through ▁the ▁interval ▁type - 2 ▁F LS , ▁due ▁to ▁the ▁( poss ibly ) ▁uncertain ▁input ▁measurements ▁that ▁have ▁activ ated ▁rules ▁whose ▁ante ced ents ▁or ▁consequ ents ▁or ▁both ▁are ▁uncertain . ▁Just ▁as ▁standard ▁deviation ▁is ▁widely ▁used ▁in ▁probability ▁and ▁statistics ▁to ▁provide ▁a ▁measure ▁of ▁un predict able ▁uncertainty ▁about ▁a ▁mean ▁value , ▁the ▁type - redu ced ▁set ▁can ▁provided ▁a ▁measure ▁of ▁uncertainty ▁about ▁the ▁cr isp ▁output ▁of ▁an ▁interval ▁type - 2 ▁F LS . ▁ ▁Comput ing ▁with ▁words ▁Another ▁application ▁for ▁f uz zy ▁sets ▁has ▁also ▁been ▁inspired ▁by ▁Prof . ▁Z ade h ▁— ▁Comput ing ▁With ▁W ords . ▁D ifferent ▁ac ron ym s ▁have ▁been ▁used ▁for ▁" comput ing ▁with ▁words ," ▁e . g ., ▁C W ▁and ▁C W W . ▁According ▁to ▁Z ade h : ▁C W W ▁is ▁a ▁method ology ▁in ▁which ▁the ▁objects ▁of ▁computation ▁are ▁words ▁and ▁propos itions ▁drawn ▁from ▁a ▁natural ▁language . ▁[ It ▁is ] ▁inspired ▁by ▁the ▁remarkable ▁human ▁cap ability ▁to ▁perform ▁a ▁wide ▁variety ▁of ▁physical ▁and ▁mental ▁tasks ▁without ▁any ▁measurements ▁and ▁any ▁comput
