fuzzy-logic
This question covers in detail, what fuzzy logic is and how it relates to other math fields, such as boolean algebra and sets theory.
This question is also very related, but the answers are focused more on general intuition and potential applicability. The only working system based on fuzzy logic, mentioned there, is MYCIN, which goes back to the early 70s. This quote from wiki summarizes my impression of it:
MYCIN was never actually used in practice.
From my experience in AI, the best tool to deal with uncertainty is Bayesian probability and inference. It allows to apply not only a wide range of probabilistic tools, such as expectation, MLE, cross-entropy, etc, but also calculus and algebra.
Can you call fuzzy logic a "pure theoretical" concept, which only played its role in the early development of AI? Are there real practical applications of fuzzy logic? What problem would you recommend to solve and to code using fuzzy logic?
