"As AI is increasingly used in future network management, the Quality-of-Trust (QoT) is a new indicator of importance in many applications. Along side established QoS metrics and emerging QoE metrics, QoT will be used to determined if the AI algorithms used in connected autonomy  is trustworthy. Here, we set out some foundations for trust and its architectural implementation in large-scale networks."  [Funded by H2020 DAWN4IoE]

"Neural Network Approximation of Graph Fourier Transforms for Sparse Sampling of Networked Flow Dynamics,"
A. Pagani, Z. Wei, R. Silva, W. Guo,
ACM Transactions on Internet Technology, to appear, Jun 2021

"Compressing networked non-linear dynamical systems is crucial to sensing complex infrastructures. Here we train deep learning to both compress (using Graph Fourier Transform as a training basis) networked non-linear dynamics of a water distribution network, and then to perform sub-GFT inference with partial data. We show neural networks can achieve acceptable noisy inference with only a small set of sensors."  [Funded by EPSRC CoTRE and Alan Turing Institute DCE Program]

"Node-Level Resilience Loss in Dynamic Complex Networks,"

Nature Scientific Reports, vol.10, 2020 [Link]
"Complex engineering and ecological systems derive sophisticated capabilities by networking together simple components. Yet, the multi-scale resilience of networked non-linear systems is not well understood. Here, we show a sequential heterogeneous mean field approach that can rapidly converge on multi-scale resilience estimation as a function of both the component level non-linear dynamics and the graph properties of the network. In particular, we show how higher order effects can cascade along the network, ending in rupture at the end of a network, yet trace causes to the beginning of a health network."  [Funded by EPSRC CoTRE]

G. Moutsinas, W. Guo,
IEEE Systems Journal, 2019 [Link]

"Seminal work to prove that load balancing stability in any network is independent of the dynamics and topology, but dependent on the accuracy of the load information. Here we use a wireless network as an example, but can be extended to other systems, and provided the self-dynamics of stations and balancing dynamics between stations are reasonable load balancing ODEs of any form, we show it is always stable for any graph topology using stochastic geometry. We further show through Gershgorin circles that the eigenvalues are bounded in stable regime only if the data accuracy that informs the load balancing has a variance that is smaller than the variance of noise."  [Funded by EPSRC CoTRE]
