Controllability of Coarsely Measured Networked Linear Dynamical Systems (Extended Version)

no code implementations21 Jun 2022 Nafiseh Ghoroghchian, Rajasekhar Anguluri, Gautam Dasarathy, Stark C. Draper

We consider the controllability of large-scale linear networked dynamical systems when complete knowledge of network structure is unavailable and knowledge is limited to coarse summaries.

Community Detection Stochastic Block Model

Quantifying the Controllability of Coarsely Characterized Networked Dynamical Systems

no code implementations29 Sep 2021 Nafiseh Ghoroghchian, Rajasekhar Anguluri, Gautam Dasarathy, Stark Draper

In contrast, in this paper the controllability aspects of the coarse system are derived from coarse summaries {\em without} knowledge of the fine-scale structure.

Graph Community Detection from Coarse Measurements: Recovery Conditions for the Coarsened Weighted Stochastic Block Model

1 code implementation25 Feb 2021 Nafiseh Ghoroghchian, Gautam Dasarathy, Stark C. Draper

Our objective is to develop conditions on the graph structure, the quantity, and properties of measurements, under which we can recover the community organization in this coarse graph.

A Hierarchical Graph Signal Processing Approach to Inference from Spatiotemporal Signals

no code implementations25 Oct 2020 Nafiseh Ghoroghchian, Stark C. Draper, Roman Genov

Such a model maps signals onto vertices of a graph and the time-space dependencies among signals are modeled by the edge weights.
