What is Fuzzy Logic?

Fuzzy Logic

What is Fuzzy Logic? Fuzzy logic measures truth values and is the contrast to Boolean logic.

Boolian Logic

In Boolean logic, the variables of truth values can only be 1 or 0, true or false. However, fuzzy logic accepts the possibility of partial truth and therefore may be any real number between 1 and 0.

While Boolean logic accurately represents how computers “think”, fuzzy logic more so represents how humans think. Fuzzy logic understands that people make decisions imprecisely and with non-numerical information. 


Through fuzzy logic, it becomes easier to explain and replicate human thought through computers. A prevalent example of how fuzzy logic and AI are used today is Natural Language Processing (NLP). We hope we’ve answered your question of “What is Fuzzy Logic?”
