In the paper, we present a general method for obtaining the OWA operator weights via extreme point approach. The extreme points are determined by the intersection of an attitudinal character constraint and a fundamental ordered weight simplex. The extreme points are completely identified by a proposed algorithm and the OWA operator weights can be expressed by a convex combination of the identified...
It has recently been shown that there is a connection between Cayley's hypdeterminant and the principal minors of a symmetric matrix. With an eye towards characterizing the entropy region of jointly Gaussian random variables, we obtain three new results on the relationship between Gaussian random variables and the hyperdeterminant. The first is a new (determinant) formula for the 2times2times2 hyperdeterminant...
