I have a table that stores all values..eg x1, x2, x3 which determines fuzzy sets. Degree of membership is assigned to each using mathematical functions for Low, Med, High.
My rule 1 states that if x1 is high AND x2 is medium then probability of output is z. I then take min{x1,x2} to evaluate the rule. Rule 2 states that if x2 is high OR x3 is medium then output is max{x2,x3}.
Now to defuzzify I take aggregation of rule consequences to find out the output of the 2 rules. I have all degrees of membership defined (0 to 1) for x1 x2 x3 for each rule.
How do I defuzzify?
