We use triangular membership functions to fuzzify the continuous gene levels of an effector e into fuzzy sets. As shown by the magenta arrow, a continuous gene level of le = 0.25 is fuzzified into the fuzzy value <L(low,le) = 0.5, L(med,le) = 0.5, L(high,le) = 0.0>. This can be reversed by defuzzification without loss of information.
