membership functions

Membership functions are tools used in fuzzy logic to represent how well a specific value fits into a particular category. Unlike traditional sets where an item either belongs or doesn't, fuzzy logic allows for degrees of membership, meaning an item can partially belong to multiple categories. The membership function assigns a score, typically between 0 and 1, indicating the degree of belonging. For example, a temperature of 75°F might have a membership of 0.8 in the "warm" category, meaning it is mostly but not fully warm. This approach allows for more nuanced decision-making and reasoning in complex systems.
