Takagi, Sugeno

Takagi-Sugeno fuzzy systems are a type of mathematical model used for complex decision-making and problem-solving. They combine fuzzy logic—allowing for reasoning with uncertain or imprecise information—with simple, often linear, rules that describe how inputs relate to outputs. Each rule has a condition (like "if temperature is high") and an associated mathematical function that predicts the outcome. When multiple rules are active, their results are weighted and combined to produce a final answer. This approach effectively manages uncertainty and nonlinear relationships, making it useful in control systems, data modeling, and pattern recognition.
