Representation and construction of homogeneous and quasi-homogeneous $n$-ary aggregation functions

Yong Su and Radko MesiarDOI: 10.14736/kyb-2021-6-0958

Abstract:

Homogeneity, as one type of invariantness, means that an aggregation function is invariant with respect to multiplication by a constant, and quasi-homogeneity, as a relaxed version, reflects the original output as well as the constant. In this paper, we characterize all homogeneous/quasi-homogeneous $n$-ary aggregation functions and present several methods to generate new homogeneous/quasi-homogeneous $n$-ary aggregation functions by aggregation of given ones.

Keywords:

homogeneity, aggregation functions, quasi-homogeneity, invariantness

Classification:
