A Fuzzy Set
A mathematical concept that extends the classical notion of a set by allowing elements to have degrees of membership instead of simply belonging or not belonging. In fuzzy sets, the degree of membership is represented by a value between 0 and 1, where 0 indicates no membership and 1 indicates full membership. This allows for a more nuanced representation of data, particularly when dealing with imprecise or vague information.

Example
For example, consider a set of people who like a particular food. In a classical set, these people would either be members or not. However, in a fuzzy set, each person could have a degree of membership between 0 and 1, reflecting the degree to which they like the food.
