SOM-based similarity index measure: quantifying interactions between multivariate structures
This paper addresses the issue of quantifying asymmetric functional relationships between signals. We specifically consider a previously proposed similarity index that is conceptually powerful, yet computationally very expensive. The complexity increases with the square of the number of samples in the signals. In order to counter this difficulty, a self-organizing map that is trained to model t...
متن کاملsimilarity measure for two densities
scott and szewczyk in technometrics, 2001, have introduced a similarity measure for twodensities f1 and f2 , by1, 21 21 1 2 2( , ), ,f fsim f ff f f f< >=< >< >wheref1, f2 f1(x, θ1)f2(x, θ2)dx.+∞−∞< >=∫sim(f1, f2) has some appropriate properties that can be suitable measures for the similarity of f1 and f2 .however, due to some restrictions on the value of parameters and the kind of densities, ...
متن کاملMultivariate Generalization of the Gauss Hypergeometric Distribution
The Gauss hypergeometric distribution with the density proportional to xα−1 (1− x)β−1 (1 + ξx)−γ , 0 < x < 1 arises in connection with the priori distribution of the parameter ρ (0 < ρ < 1) representing traffic intensity in a M/M/1 queue system. In this article, we define and study a multivariate generalization of this distribution and derive some of its properties like marginal densities, join...
متن کاملThe Structure of Multivariate Hypergeometric Terms
The structure of multivariate hypergeometric terms is studied. This leads to a proof of (a special case of) a conjecture formulated by Wilf and Zeilberger in 1992. A function u(n1, . . . , nd) with values in a field K is called a hypergeometric term if there exist rational functions Ri ∈ K(n1, . . . , nd), i = 1, . . . , d, such that u is solution of a system of d firstorder recurrences Si · u ...
متن کاملOn the Structure of Multivariate Hypergeometric Terms
Wilf and Zeilberger conjectured in 1992 that a hypergeometric term is proper-hypergeometric if and only if it is holonomic. We prove a slightly modiied version of this conjecture in the case of several discrete variables.
