A Type-2 Fuzzy Classifier: (a) A two-dimensional cluster in the feature space and the corresponding T1 fuzzy rule. (b) Footprint of a Gaussian interval type-2 fuzzy set with uncertain mean m∈[m 1 ,m 2 ]. (c) Illustrative comparison of a one-rule T2FLS and T1FLS-based classifiers (Δm and Δc define the initial bounds of uncertainty modeled in the system. (d) Structure of a sample T2 fuzzy rule base (the domain of the antecedents' membership functions is normalised).
