Median evidential c-means algorithm and its application to community detection [PDF]

, 2015
Median clustering is of great value for partitioning relational data. In this paper, a new prototype-based clustering method, called Median Evidential C-Means (MECM), which is an extension of median c-means and median fuzzy c-means on the theoretical ...

Generalized Fuzzy Graph Connectivity Parameters with Application to Human Trafficking

Mathematics, 2020
Graph models are fundamental in network theory. But normalization of weights are necessary to deal with large size networks like internet. Most of the research works available in the literature have been restricted to an algorithmic perspective alone ...

A similarity-based community detection method with multiple prototype representation [PDF]

, 2015
Communities are of great importance for understanding graph structures in social networks. Some existing community detection algorithms use a single prototype to represent each group.

q-Rung Orthopair Fuzzy Competition Graphs with Application in the Soil Ecosystem

Mathematics, 2019
The q-rung orthopair fuzzy set is a powerful tool for depicting fuzziness and uncertainty, as compared to the Pythagorean fuzzy model. The aim of this paper is to present q-rung orthopair fuzzy competition graphs (q-ROFCGs) and their generalizations ...

Interval-valued fuzzy graphs

, 2012
We define the Cartesian product, composition, union and join on interval-valued fuzzy graphs and investigate some of their properties. We also introduce the notion of interval-valued fuzzy complete graphs and present some properties of self complementary

On Strong Intervals in Fuzzy Graphs

Fuzzy Information and Engineering, 2017
Intervals and convexity play crucial roles in the applications of graph theory such as town planning and design of graphics. In this article, the concept of geodetic interval in graphs is extended to fuzzy graphs.

Using intelligent optimization methods to improve the group method of data handling in time series prediction [PDF]

, 2008
In this paper we show how the performance of the basic algorithm of the Group Method of Data Handling (GMDH) can be improved using Genetic Algorithms (GA) and Particle Swarm Optimization (PSO).

Some novel concepts of intuitionistic fuzzy directed graphs with application in selecting a suitable place for opening restaurant

Heliyon
In this manuscript, we first initiate several types of effective arcs of intuitionistic fuzzy directed graphs, followed by discussions on different types of dominations in intuitionistic fuzzy directed graphs and their application in decision-making. The
