Network Structure Inference, A Survey: Motivations, Methods, and Applications [article]

Ivan Brugere and Brian Gallagher and Tanya Y. Berger-Wolf
2018 arXiv   pre-print
Existing approaches for inferring networks from data are found across many application domains and use specialized knowledge to infer and measure the quality of inferred network for a specific task or  ...  In this survey, we examine (1) how network representations are constructed from underlying data, (2) the variety of questions and tasks on these representations over several domains, and (3) validation  ...  For example, a social network defined via thresholding on who-calls-whom call record data is more interpretable than a linear regression on node feature vectors.  ...
