A Review of Random Walk-Based Method for the Identification of Disease Genes and Disease Modules

open access: yesIEEE Access, 2023
Traditional techniques for identifying disease genes and disease modules involve high-cost clinical experiments and unpredictable time consumption for analysis.

Tracking random walks [PDF]

open access: yesJournal of The Royal Society Interface, 2018
In empirical studies, trajectories of animals or individuals are sampled in space and time. Yet, it is unclear how sampling procedures bias the recorded data. Here, we consider the important case of movements that consist of alternating rests and moves of random durations and study how the estimate of their statistical properties is affected by the way

A phase transition in the random transposition random walk [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
Our work is motivated by Bourque-Pevzner's simulation study of the effectiveness of the parsimony method in studying genome rearrangement, and leads to a surprising result about the random transposition walk in continuous time on the group of ...

Random walks on the random graph [PDF]

open access: yesThe Annals of Probability, 2018
We study random walks on the giant component of the Erdős–Rényi random graph G(n,p) where p=λ/n for λ>1 fixed. The mixing time from a worst starting point was shown by Fountoulakis and Reed, and independently by Benjamini, Kozma and Wormald, to have order log2n.

Convolutional Random Walk Networks for Semantic Image Segmentation [PDF]

open access: yesComputer Vision and Pattern Recognition, 2016
Most current semantic segmentation methods rely on fully convolutional networks (FCNs). However, their use of large receptive fields and many pooling layers cause low spatial resolution inside the deep layers.

A martingale approach for the elephant random walk [PDF]

open access: yes, 2017
The purpose of this paper is to establish, via a martingale approach, some refinements on the asymptotic behavior of the one-dimensional elephant random walk (ERW).

Dirichlet Random Walks [PDF]

open access: yesJournal of Applied Probability, 2014
This paper provides tools for the study of the Dirichlet random walk in Rd. We compute explicitly, for a number of cases, the distribution of the random variable W using a form of Stieltjes transform of W instead of the Laplace transform, replacing the Bessel functions with hypergeometric functions. This enables us to simplify some existing results, in

Random Walk on the Range of Random Walk [PDF]

open access: yesJournal of Statistical Physics, 2009
We study the random walk $X$ on the range of a simple random walk on $\mathbb{Z}^d$ in dimensions $d\geq 4$. When $d\geq 5$ we establish quenched and annealed scaling limits for the process $X$, which show that the intersections of the original simple random walk path are essentially unimportant.

Multifractal random walk [PDF]

open access: yesPhysical Review E, 2001
We introduce a class of multifractal processes, referred to as Multifractal Random Walks (MRWs). To our knowledge, it is the first multifractal processes with continuous dilation invariance properties and stationary increments. MRWs are very attractive alternative processes to classical cascade-like multifractal models since they do not involve any ...
