Accuracy evaluation of soft classifiers using interval type-2 fuzzy sets framework
Elisabetta Binaghi, Alberto Arturo Vergani, Valentina Pedoia · 2017
This paper proposes a new accuracy evaluation method within a behavioral comparison strategy which uses interval type-2 fuzzy sets and derived operations to model reference data and define soft accuracy indexes. The method addresses the case in which grades of membership, collected by surveying experts, will often be different for the same reference pattern, because the experts will not necessarily be in agreement. The approach is illustrated using simple examples and an application in the domain of biomedical image segmentation.
