I scaned alot of fuzzy liternatures and I came across "Centroid" and
"Center of Gravity" defuzzification methods. Are they the same thing?
For instance, I came across a defuzzification method that defuzzify
using weighted sum where weights are the area of each truncated membership
functions, while another method where weight is the degree of membership
of each fuzzy subset. What are these methods called? Are there more
varieties of "center of gravity" methods?
