Information Inequalities via Submodularity and a Problem in Extremal Graph Theory

open access: yesEntropy, 2022
The present paper offers, in its first part, a unified approach for the derivation of families of inequalities for set functions which satisfy sub/supermodularity properties.

Graph Analysis Using Fast Fourier Transform Applied on Grayscale Bitmap Images

open access: yesInformation, 2021
There is spiking interest in graph analysis, mainly sparked by social network analysis done for various purposes. With social network graphs often achieving very large size, there is a need for capable tools to perform such an analysis.

A note on graph theory techniques for brain tumor detection [PDF]

open access: yesRomanian Journal of Neurology, 2022
Brain Tumors are detected in people of all age groups. It leads to various complications that are both physiological and psychological. Graph theory techniques are employed to study both functional and structural behavior of brain networks.

Towards Inferring Influential Facebook Users

open access: yesComputers, 2021
Because of the complexity of the actors and the relationships between them, social networks are always represented by graphs. This structure makes it possible to analyze the effectiveness of the network for the social actors who are there.

Kolmogorov Basic Graphs and Their Application in Network Complexity Analysis

open access: yesEntropy, 2021
Throughout the years, measuring the complexity of networks and graphs has been of great interest to scientists. The Kolmogorov complexity is known as one of the most important tools to measure the complexity of an object.

Graph equations for line graphs, total graphs, middle graphs and quasi-total graphs

open access: yesDiscrete Mathematics, 1984
Let G be a simple finite and connected graph with the vertex set V(G) and the edge set X(G). Let V'(G) be the family of all one-point subsets of V(G). Both the line graph L(G) of G and the total graph T(G) of G are standard graph theoretical concepts. The middle graph M(G) of G is the intersection graph of \(V'(G)\cup X(G)\) and the quasi-total graph P(

Concepts and Practice of Statistics: Part 3 - Graphics

open access: yesAustralasian Orthodontic Journal, 1987
The process of analysis of a set data aims to detect patterns, especially relationships between variables, in the data. Statistical techniques can be described broadly as techniques to detect particular types of patterns, and to test whether such ...
