山东大学数学学院运筹学英文课件chap3 The Simplex Method and Sensitivity Analysis。
In this paper we discuss a novel framework for multiclass learning, defined by a suitable coding/decoding strategy, namely the simplex coding, that allows to generalize to multiple classes a relaxatio...
The local $h$-vector of the cluster subdivision of a simplex
Local h-vector barycentric subdivision cluster complex cluster subdivision
2012/4/18
The cluster complex $\Delta (\Phi)$ is an abstract simplicial complex, introduced by Fomin and Zelevinsky for a finite root system $\Phi$. The positive part of $\Delta (\Phi)$ naturally defines a simp...
Abstract: We determine the mixing time of a simple Gibbs sampler on the unit simplex, confirming a conjecture of D. Aldous. The upper bound is based on a two-step coupling, where the first step is a s...
Incomplete Hypergeometric Systems Associated to 1-Simplex $\times$ (n-1)-Simplex
Incomplete Hypergeometric Systems 1-Simplex $\times$ (n-1)-Simplex
2011/2/22
The A-hypergeometric system was introduced by Gel’fand, Kapranov and Zelevinsky in the 1980’s. Among several classes of A-hypergeometric functions, those for 1-simplex × (n − 1)-simplex are know...
A note about the uniform distribution on the intersection of a simplex and a sphere
uniform distribution sphere
2010/11/23
Uniform probability distributions on $\ell_p$ balls and spheres have been studied extensively and are known to behave like product measures in high dimensions. In this note we consider the uniform di...
The Lattice and Simplex Structure of States on Pseudo Effect Algebras
Pseudo effect algebra effect algebra Riesz Decomposition Properties
2010/11/30
We study states, measures, and signed measures on pseudo effect algebras with some kind of the Riesz Decomposition Property, (RDP). We show that the set of all Jordan signed measures is always an Abel...
Improved Inclusion-Exclusion Inequalities for Simplex and Orthant Arrangements
Orthant Arrangments Inclusion-Exclusion
2008/7/1
Improved inclusion-exclusion inequalities for unions of sets are available wherein terms usually included in the alternating sum formula can be left out. This is the case when a key abstract tube con...
In this paper, we study a problem of geometric inequalities for an n-simplex. Some new geometric inequalities for a simplex are established. As special cases, some known inequalities are deduced.
Inequalities for Inscribed Simplex and Applications
Simplex Inscribed simplex Inradius Circumradius Inequality
2008/7/1
In this paper, we study the problem of geometric inequalities for the inscribed simplex of an n-dimensional simplex. An inequality for the inscribed simplex of a simplex is established. Applying it we...
In this paper, a modification of the bisection simplex
method$^{[7]}$ is made for more general purpose use. Organized in an
alternative simpler form, the modified version exploits information of the...
Simplex Codes Over the Ring \sumn=0sun F2
Simplex codes chain rings Zps-codes and \sumn=0n=sun F2-linear codes
2010/2/26
In this paper, we introduce simplex linear codes over the ring \sumn=0n=sun F2 of types a and b, where us+1=0. And we determine their properties. These codes are an extension and generalization of sim...
