Simple Random Walks on Trees

European Journal of Combinatorics, 1986
Let T be a locally finite, infinite tree. The simple random walk on T is the Markov chain on T with transition probabilities \(p(v,w)=1/d(v)\) if v, w are adjacent vertices, and \(p(v,w)=0\) otherwise, where d(v) is the degree of the vertex v. In this paper the authors investigate recurrence properties of tree and relations between the radius of ...

Random Intersection Trees

, 2013
Finding interactions between variables in large and high-dimensional datasets is often a serious computational challenge. Most approaches build up interaction sets incrementally, adding variables in a greedy fashion. The drawback is that potentially informative high-order interactions may be overlooked.

Stand spatial structure and productivity based on random structural unit in Larix principis‐rupprechtii forests

Ecosphere
Stand spatial structure plays a key role in forest management, and in particular the random structural unit, comprising random tree and its neighbors, largely determines forest stability and its productivity.

Exiting measures for random walks on infinite rooted trees

Nonautonomous Dynamical Systems
We consider conformal iterated function systems (CIFS) that are induced by an infinite rooted tree TT, which we call TT-conformal iterated function systems (TT-CIFS).

XCO₂ Super-Resolution Reconstruction Based on Spatial Extreme Random Trees

Atmosphere
Carbon dioxide (CO2) is currently the most harmful greenhouse gas in the atmosphere. Obtaining long-term, high-resolution atmospheric column CO2 concentration (XCO2) datasets is of great practical significance for mitigating the greenhouse effect ...
