摘要: A new distance function for fuzzy sets is introduced. It based on the descriptive complexity, that is, number of bits (on average) are needed to describe an element in symmetric difference two sets. The value gives amount additional information either one when other known. We prove a pseudo-metric, namely, it non-negative, symmetric, equals zero if identical and satisfies triangle inequality.
