Tree networks with causal structure [PDF]

Physical Review E, 2003
Geometry of networks endowed with a causal structure is discussed using the conventional framework of equilibrium statistical mechanics. The popular growing network models appear as particular causal models. We focus on a class of tree graphs, an analytically solvable case.

Spectra of Self-Similar Measures

Entropy, 2022
This paper is devoted to the characterization of spectrum candidates with a new tree structure to be the spectra of a spectral self-similar measure μN,D generated by the finite integer digit set D and the compression ratio N−1.

Closeness of some tree structures

Soft Computing, 2022
Abstract A graph can be analyzed by means of many graph theoretical parameters and formulas derived from them. One of those parameters is the closeness parameter which is modified to enable calculations in disconnected graphs. In thispaper, we have considered closeness of some tree structures as k-ary tree, binomial trees, binary tree, comet ...

Signature-based Tree for Finding Frequent Itemsets

Journal of Communications Software and Systems, 2023
The efficiency of a data mining process depends on the data structure used to find frequent itemsets. Two approaches are possible: use the original transaction dataset or transform it into another more compact structure.

Discrimination of Leaves in a Multi-Layered Mediterranean Forest through Machine Learning Algorithms

Remote Sensing, 2023
Terrestrial laser scanning (TLS) technology characterizes standing trees with millimetric precision. An important step to accurately quantify tree volume and above-ground biomass using TLS point clouds is the discrimination between timber and leaf ...

Filtering Stems and Branches from Terrestrial Laser Scanning Point Clouds Using Deep 3-D Fully Convolutional Networks

Remote Sensing, 2018
Terrestrial laser scanning (TLS) can produce precise and detailed point clouds of forest environment, thus enabling quantitative structure modeling (QSM) for accurate tree morphology and wood volume allocation. Applying QSM to plot-scale wood delineation
