Explore fuzzy logic as a framework for reasoning under vagueness. Learn fuzzy sets, membership functions, fuzzy operators, and rule-based inference with clear theory and concise NumPy examples.

Discover the limitations of classical logic and the motivation for fuzzy logic. Learn how fuzzy sets and degrees of truth enable reasoning under vagueness.

Model vagueness numerically using membership functions. Learn to design, visualize, and interpret fuzzy sets.

Delve into fuzzy logical operators, t-norms, t-conorms, and how fuzzy rules are composed.

Integrate fuzzy rules into inference systems and perform approximate reasoning.
