Information Before Split (IBS) klasslar sonidan kelib chiqib hisoblanadi. Misol uchun Yes-9, No-5 bo’ladigan bo’lsa unda IBS quyidagicha hisoblanadi: Info([5, 9])= Entropy(5/14, 9/14)= -5/14*log2(5/14)-9/14*log2(9/14)=0.940. Misollarda ko’p uchraydigan logarifmik ifodalarni (Entropy)ni yechish mumkin.
