Imodeli enegalelo, iziphumo, kunye nomsebenzi obonakalayo nowaziwayo, kodwa uzalisekiso lwangaphakathi alwaziwa okanye alulunganga, umzekelo, imodeli eyenziwe ngekhompyutha yokubuyisa itshintshi kumatshini wokuthengisa, engendlela yetafile ebonisa ixabiso letshintshi ekumele ukuba ibuye kwimali nganye efakiweyo. I-Syn: igalelo/isiphumo semodeli. Umahluko onemodeli yebhokisi yeglasi. [DIS; IEEE]
