Application of Langevin Dynamics to Advance the Quantum Natural Gradient Optimization Algorithm
Oleksandr Borysenko, Mykhailo Bratchenko, Ilya Lukin +4
A Quantum Natural Gradient (QNG) algorithm for optimization of variational quantum circuits has been proposed recently. In this study, we employ the Langevin equation with a QNG st…
Improving exponential-family random graph models for bipartite networks
Alex Stivala, Peng Wang, Alessandro Lomi
Bipartite graphs, representing two-mode networks, arise in many research fields. These networks have two disjoint node sets representing distinct entity types, for example persons…
ALAAMEE: Open-source software for fitting autologistic actor attribute models
Alex Stivala, Peng Wang, Alessandro Lomi
The autologistic actor attribute model (ALAAM) is a model for social influence, derived from the more widely known exponential-family random graph model (ERGM). ALAAMs can be used…
Relational hyperevent models for the coevolution of coauthoring and citation networks
Jürgen Lerner, Marian-Gabriel Hâncean, Alessandro Lomi
The development of suitable statistical models for the analysis of bibliographic networks has trailed behind the empirical ambitions expressed by recent studies of science of scien…
