  1. 1. The configuration model for multi-layer networksformation

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Katarzyna Kowalczyk; [2021]
    Keywords : ;

    Abstract : Generating synthetic network data is a significant part of network analysis. One of the main challenges in generating synthetic networks is to preserve features observed inreality. For a long time, our social connections were mostly simulated by graphs, imitating some features, e.g. READ MORE

  3. 2. Decentralized Diffusion-Controlled Algorithm for Community Detection : Initialization and Resolution Study

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Adrian Ramirez; [2017]
    Keywords : community detection; unbalanced communities; adaptive diffusion; decentralized algorithm; Gemenskap detektering; obalanda gemenskaper; adaptativ diffusion; decentraliserad algoritm;

    Abstract : Community detection in graphs has been an important research topic for many fields. The aim of community detection is to extract from graphs those groups of nodes that present more connections between them than with the rest of the network. Detecting such groups at different scales can help understanding the global behaviour of the system. READ MORE

  4. 3. Clustering in Financial Markets : A Network Theory Approach
