Novel methods of measuring the similarity and distance between complex fuzzy sets
McCulloch, Josie C. (2016) Novel methods of measuring the similarity and distance between complex fuzzy sets. PhD thesis, University of Nottingham.
This thesis develops measures that enable comparisons of subjective information that is represented through fuzzy sets. Many applications rely on information that is subjective and imprecise due to varying contexts and so fuzzy sets were developed as a method of modelling uncertain data. However, making relative comparisons between data-driven fuzzy sets can be challenging. For example, when data sets are ambiguous or contradictory, then the fuzzy set models often become non-normal or non-convex, making them difficult to compare.
