The spectral dimension of random trees

open access: yes, 2002
We present a simple yet rigorous approach to the determination of the spectral dimension of random trees, based on the study of the massless limit of the Gaussian model on such trees.

Random enriched trees with applications to random graphs

open access: yes, 2016
We establish limit theorems that describe the asymptotic local and global geometric behaviour of random enriched trees considered up to symmetry. We apply these general results to random unlabelled weighted rooted graphs and uniform random unlabelled $k$-

Random model trees: an effective and scalable regression method [PDF]

open access: yes, 2010
We present and investigate ensembles of randomized model trees as a novel regression method. Such ensembles combine the scalability of tree-based methods with predictive performance rivaling the state of the art in numeric prediction.

Developent of stem taper equation using nonlinear mixed-effects modeling approach for Taurus fir

open access: yesTurkish Journal of Forestry, 2018
The Max and Burkhart segmented taper equation was fitted using nonlinear mixed-effects modeling techniques to account for within- and between-individual variation in Taurus fir (Abies cilicica Carr.) stem profiles.

Random recursive trees and the elephant random walk [PDF]

open access: yesPhysical Review E, 2016
One class of random walks with infinite memory, so called elephant random walks, are simple models describing anomalous diffusion. We present a surprising connection between these models and bond percolation on random recursive trees. We use a coupling between the two models to translate results from elephant random walks to the percolation process. We
