Scaled Null-Adjusted Persistence: A Multiscale Bridge between Modularity and Persistence
Alessandro Avellone, Paolo Bartesaghi, Stefano Benati +1
Community detection methods must balance two competing objectives: identifying small, cohesive groups while avoiding excessive fragmentation. Modularity, the most widely adopted op…
Null-adjusted persistence function for high-resolution community detection
Alessandro Avellone, Paolo Bartesaghi, Stefano Benati +2
Modularity and persistence probability are two widely used quality functions for detecting communities in complex networks. In this paper, we introduce a new objective function cal…
A Mathematical Programming approach to Overlapping community detection by cluster's Shapley value
Stefano Benati, Justo Puerto, Antonio M. Rodríguez-Chía +1
We propose a new model to detect the overlapping communities of a network that is based on cooperative games and mathematical programming. More specifically, communities are define…
A Network Model for Multiple Selection Questions in Opinion Surveys
Stefano Benati, Justo Puerto
Opinion surveys can contain closed questions to which respondents can give multiple answers. We propose to model these data as networks in which vertices are eligible items and arc…
On Finding the Community with Maximum Persistence Probability
Alessandro Avellone, Stefano Benati, Rosanna Grassi +1
The persistence probability is a statistical index that has been proposed to detect one or more communities embedded in a network. Even though its definition is straightforward, e.…
A Branch-and-price procedure for clustering data that are graph connected
Stefano Benati, Diego Ponce, Justo Puerto +1
This paper studies the Graph-Connected Clique-Partitioning Problem (GCCP), a clustering optimization model in which units are characterized by both individual and relational data.…
Multi-attribute community detection in International Trade Network
Paolo Bartesaghi, Stefano Benati, Gian Paolo Clemente +1
Understanding the structure of communities in a network has a great importance in the economic analysis. Communities are indeed characterized by specific properties, that are diffe…
