Gramian-Based Adaptive Combination Policies for Diffusion Learning over Networks
Y. Efe Erginbas, Stefan Vlaski, Ali H. Sayed
This paper presents an adaptive combination strategy for distributed learning over diffusion networks. Since learning relies on the collaborative processing of the stochastic infor…
Adaptive Social Learning
Virginia Bordignon, Vincenzo Matta, Ali H. Sayed
This work proposes a novel strategy for social learning by introducing the critical feature of adaptation. In social learning, several distributed agents update continually their b…
Second-Order Guarantees in Centralized, Federated and Decentralized Nonconvex Optimization
Stefan Vlaski, Ali H. Sayed
Rapid advances in data collection and processing capabilities have allowed for the use of increasingly complex models that give rise to nonconvex optimization problems. These formu…
Learning Graph Influence from Social Interactions
Vincenzo Matta, Virginia Bordignon, Augusto Santos +1
In social learning, agents form their opinions or beliefs about certain hypotheses by exchanging local information. This work considers the recent paradigm of weak graphs, where th…
