New publication in Physical Review X
The latest contribution of Dynamica has just been published in Physical Review X. The project originates from a workshop in Charlevoix in September 2016, involving current Dynamica members (G. St-Onge, E. Laurence, C. Murphy, P. Desrosiers) and alumni, Jean-Gabriel Young and Laurent Hébert-Dufresne.
The paper titled Phase Transition in the Recoverability of Network History explores the very difficult Network Archaeology problem : reconstructing the past states of a growing network from a single static snapshot. Formulated as Bayesian inference task, a state-of-the-art sequential Monte Carlo method is developed to estimate the posterior distribution, used to identify and characterize a phase transition in the quality of the reconstructed history.
