Comparison of the tests presented in "TEST SET B" (changes were realized in the membership functions of the entry set and its fuzzy sets)

Tests	Type of membership function (after adjustments in fuzzy sets)	Sensitivity (%)	Specificity (%)
PDM-FNA-Fuzzy developed	trapezoidal (1)	98.59	85.43
Test B.1	triangular(2)	98.59	83.47
Test B.2	gaussian2(3)	98.11	84.31
Test B.3	dsigmoidal(4)	98.11	84.59
Test B.4	polinomial zero(5)	98.59	82.91

(1) trapezoidal - function with straight lines with a flat top, resembling a truncated triangle.

(2) triangular - function with straight lines, in the form of a triangle.

(3) gaussiana2 - composed of two different gaussian curves.

(4) dsigmoidal - created from the difference between two sigmoidais functions.

(5) polinomial zero – asymmetric polynomial function, being zero at both ends, with an increase in the middle.
