Convergence rate of Riemannian Hamiltonian Monte Carlo and faster polytope volume computation [PDF]

open access: yesSymposium on the Theory of Computing, 2017
We give the first rigorous proof of the convergence of Riemannian Hamiltonian Monte Carlo, a general (and practical) method for sampling Gibbs distributions.

Robustness of Magic and Symmetries of the Stabiliser Polytope [PDF]

open access: yesQuantum, 2018
We give a new algorithm for computing therobustness of magic- a measure of the utility of quantum states as a computational resource. Our work is motivated by themagic state modelof fault-tolerant quantum computation.

On expected number of maximal points in polytopes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
We answer an old question: what are possible growth rates of the expected number of vector-maximal points in a uniform sample from a polytope.

The Relationship between the Stasheff Polytope and Painted Trees Using Tubings [PDF]

open access: yesEngineering and Technology Journal, 2016
A polytope plays a central role in different areas of mathematics. It is used quite heavily in applied fields of mathematics, such as medical imaging and robotics, geometric modeling. A polytope has many users in modern science such as computer graphics,

Flag enumerations of matroid base polytopes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
In this paper, we study flag structures of matroid base polytopes. We describe faces of matroid base polytopes in terms of matroid data, and give conditions for hyperplane splits of matroid base polytopes.

Newton polytope of good symmetric polynomials

open access: yesComptes Rendus. Mathématique, 2023
We introduce a general class of symmetric polynomials that have saturated Newton polytope and their Newton polytope has integer decomposition property. The class covers numerous previously studied symmetric polynomials.

Polytope Conditioning and Linear Convergence of the Frank-Wolfe Algorithm [PDF]

open access: yesMathematics of Operations Research, 2015
It is known that the gradient descent algorithm converges linearly when applied to a strongly convex function with Lipschitz gradient. In this case the algorithm's rate of convergence is determined by the condition number of the function.

Sparse Representation of a Polytope and Recovery of Sparse Signals and Low-Rank Matrices [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
This paper considers compressed sensing and affine rank minimization in both noiseless and noisy cases and establishes sharp restricted isometry conditions for sparse signal and low-rank matrix recovery. The analysis relies on a key technical tool, which

Computing The Number of Integral Points in4-dimensional Ball Using Tutte Polynomial [PDF]

open access: yesEngineering and Technology Journal, 2015
In recent years, the uses of high dimensional appear in a large and a lot of applications appearwithin it. So, we study these applications and take one of them that play a central role in the factoring of prime number which is an application especially ...
