fuzzy rule-based systems

Fuzzy rule-based systems are decision-making tools that mimic human reasoning by handling vague or uncertain information. Instead of strict yes-or-no logic, they use "fuzzy" concepts—like "somewhat hot" or "very tall"—to evaluate conditions. These systems apply a set of rules, such as "If temperature is high, then fan speed is fast," to make decisions or predictions. They are useful in complex, real-world situations where things aren’t strictly black or white, allowing for more flexible and human-like responses.
