Expert interpretation of bar and line graphs: The role of graphicacy in reducing the effect of graph format. [PDF]

, 2015
The distinction between informational and computational equivalence of representations, first articulated by Larkin and Simon (1987) has been a fundamental principle in the analysis of diagrammatic reasoning which has been supported empirically on ...

Tight Frame Graphs Arising as Line Graphs

The PUMP Journal of Undergraduate Research, 2021
Dual multiplicity graphs are those simple, undirected graphs that have a weighted Hermitian adjacency matrix with only two distinct eigenvalues.  From the point of view of frame theory, their characterization can be restated as which graphs have a representation by a tight frame.

LeL-GNN: Learnable Edge Sampling and Line Based Graph Neural Network for Link Prediction

IEEE Access, 2023
Graph neural networks lose a lot of their computing power when more network layers are added. As a result, the majority of existing graph neural networks have a shallow depth of learning. Over-smoothing and information loss are two of the key issues that

Generative Service Provisioning for IoT Devices Using Line Graph Structure

IEEE Access, 2023
A service subgraph helps Internet-of-Things devices access resources in a dynamic Internet-of-Things device network. We propose a service subgraph generation method for Internet-of-Things device networks.

BOREL LINE GRAPHS

The Journal of Symbolic Logic
Abstract We characterize Borel line graphs in terms of 10 forbidden induced subgraphs, namely the nine finite graphs from the classical result of Beineke together with a 10th infinite graph associated with the equivalence relation $\mathbb {E}_0$ on the Cantor space.

Some Properties of Regular Line Graphs

مجلة علوم ذي قار, 2019
In this paper, the concept of regular line graph has been introduced. The maximum number of vertices with different degrees in the regular line graphs has also been studied.

Randić Index of a Line Graph

Axioms, 2022
The Randić index of a graph G, denoted by R(G), is defined as the sum of 1/d(u)d(v) for all edges uv of G, where d(u) denotes the degree of a vertex u in G. In this note, we show that R(L(T))>n4 for any tree T of order n≥3.

Scattering theory and discrete-time quantum walks

, 2004
We study quantum walks on general graphs from the point of view of scattering theory. For a general finite graph we choose two vertices and attach one half line to each.

Detection and classification of transmission line transient faults based on graph convolutional neural network

CSEE Journal of Power and Energy Systems, 2021
We present a novel transient fault detection and classification approach in power transmission lines based on graph convolutional neural network. Compared with the existing techniques, the proposed approach considers explicit spatial information in ...
