    Sammanfattning : We live in an interconnected world full of complex systems that cannot be understood simply by analyzing their components. From how genes regulate biological functions to the distribution of life on Earth, we need methods that can analyze systems as a whole. LÄS MER

  4. 3. Through the coding-lens : community detection and beyond

    Författare :Christopher Blöcker; Martin Rosvall; Juan Carlos Nieves; Jari Saramäki; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; community detection; map equation; Huffman coding; network centrality; link prediction;

    Sammanfattning : We live in a highly-connected world and find networks wherever we look: social networks, public transport networks, telecommunication networks, financial networks, and more. These networks can be immensely complex, comprising potentially millions or even billions of inter-connected objects. LÄS MER

  5. 4. Selected Topics in Mathematical Modelling: Machine Learning and Tugs-of-War
