Self-reinforcing cascades: A spreading model for beliefs or products of varying intensity or quality
Laurent Hébert-Dufresne, Juniper Lovato, Giulio Burgio +3
Models of how things spread often assume that transmission mechanisms are fixed over time. However, social contagions--the spread of ideas, beliefs, innovations--can lose or gain i…
Robustness and resilience of complex networks
Oriol Artime, Marco Grassia, Manlio De Domenico +5
Complex networks are ubiquitous: a cell, the human brain, a group of people and the Internet are all examples of interconnected many-body systems characterized by macroscopic prope…
Time-dependent influence metric for cascade dynamics on networks
James P. Gleeson, Ailbhe Cassidy, Daniel Giles +1
An algorithm for efficiently calculating the expected size of single-seed cascade dynamics on networks is proposed and tested. The expected size is a time-dependent quantity and so…
Systematic comparison of deep generative models applied to multivariate financial time series
Howard Caulfield, James P. Gleeson
Financial time series (FTS) generation models are a core pillar to applications in finance. Risk management and portfolio optimization rely on realistic multivariate price generati…
