Pruned Discrete Random Samples [PDF]

open access: yesJournal of Applied Probability, 2013
Let Xi,i ∈ ℕ, be independent and identically distributed random variables with values in ℕ0. We transform (‘prune’) the sequence {X1,…,Xn},n∈ ℕ, of discrete random samples into a sequence {0,1,2,…,Yn}, n∈ ℕ, of contiguous random sets by replacing Xn+1 with Yn +1 if Xn+1 >Yn. We consider the asymptotic behaviour of Yn as n→∞.

Pricing Variance Swaps under MRG Model with Regime-Switching: Discrete Observations Case

open access: yesMathematics, 2023
In this paper, we creatively price the discretely sampled variance swaps under the mean-reverting Gaussian model (MRG model in short) with regime-switching asymmetric double exponential jump diffusion.

Constant-time Implementation Method for Discrete Gaussian Sampling on Integer [PDF]

open access: yesJisuanji gongcheng, 2020
Discrete Gaussian sampling on integer is the basic operation implemented by lattice cryptosystems,and is also a determinant factor of security,but it may be subject to timing attacks and cause the leakage of secret information.To address the problem,this

Improved Bernoulli Sampling for Discrete Gaussian Distributions over the Integers

open access: yesMathematics, 2021
Discrete Gaussian sampling is one of the fundamental mathematical tools for lattice-based cryptography. In this paper, we revisit the Bernoulli(-type) sampling for centered discrete Gaussian distributions over the integers, which was proposed by Ducas et

Gaps in Discrete Random Samples [PDF]

open access: yesJournal of Applied Probability, 2009
Let (Xi)i∈ℕ be a sequence of independent and identically distributed random variables with values in the set ℕ0 of nonnegative integers. Motivated by applications in enumerative combinatorics and analysis of algorithms we investigate the number of gaps and the length of the longest gap in the set {X1,…,Xn} of the first n values. We obtain necessary and

Discrete-time randomized sampling [PDF]

open access: yesICECS 2001. 8th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.01EX483), 2002
This paper explores the use of randomized sampling in implementing convolution in discrete-time with application to the areas of approximate filtering, low-power filter design, and hardware failure modeling. Three distinct randomized sampling methods are presented and additive error models as well as second-order error statistics are derived for these ...
