Topology Inference over Networks with Nonlinear Coupling
Augusto Santos, Vincenzo Matta, Ali H. Sayed
This work examines the problem of topology inference over discrete-time nonlinear stochastic networked dynamical systems. The goal is to recover the underlying digraph linking the…

Thermodynamic Limit of Interacting Particle Systems over Time-varying Sparse Random Networks
Augusto Almeida Santos, Soummya Kar, José M. F. Moura +1
We establish a functional weak law of large numbers for observable macroscopic state variables of interacting particle systems (e.g., voter and contact processes) over fast time-va…

Strong Attractors in Stochastic Adaptive Networks: Emergence and Characterization
Augusto Almeida Santos, Soummya Kar, Ramayya Krishnan +1
We propose a family of models to study the evolution of ties in a network of interacting agents by reinforcement and penalization of their connections according to certain local la…
