How Complex is a Complex Network? Insights from Linear Systems Theory
Giacomo Baggio, Marco Fabris
This paper leverages linear systems theory to propose a principled measure of complexity for network systems. We focus on a network of first-order scalar linear systems interconnec…
Data-driven Eigenstructure Assignment for Sparse Feedback Design
Federico Celi, Giacomo Baggio, Fabio Pasqualetti
This paper presents a novel approach for solving the pole placement and eigenstructure assignment problems through data-driven methods. By using open-loop data alone, the paper sho…
Dissipative Encoding of Quantum Information
Giacomo Baggio, Francesco Ticozzi, Peter D. Johnson +1
We formalize the problem of dissipative quantum encoding, and explore the advantages of using Markovian evolution to prepare a quantum code in the desired logical space, with empha…
Functional Control of Oscillator Networks
Tommaso Menara, Giacomo Baggio, Danielle S. Bassett +1
Oscillatory activity is ubiquitous in natural and engineered network systems. The interaction scheme underlying interdependent oscillatory components governs the emergence of netwo…

Data-Driven Control of Complex Networks
Giacomo Baggio, Danielle S. Bassett, Fabio Pasqualetti
Our ability to manipulate the behavior of complex networks depends on the design of efficient control algorithms and, critically, on the availability of an accurate and tractable m…
A Framework to Control Functional Connectivity in the Human Brain
Tommaso Menara, Giacomo Baggio, Danielle S. Bassett +1
In this paper, we propose a framework to control brain-wide functional connectivity by selectively acting on the brain's structure and parameters. Functional connectivity, which me…
Efficient Communication over Complex Dynamical Networks: The Role of Matrix Non-Normality
Giacomo Baggio, Virginia Rutten, Guillaume Hennequin +1
In both natural and engineered systems, communication often occurs dynamically over networks ranging from highly structured grids to largely disordered graphs. To use, or comprehen…

Stability Conditions for Cluster Synchronization in Networks of Heterogeneous Kuramoto Oscillators
Tommaso Menara, Giacomo Baggio, Danielle S. Bassett +1
In this paper we study cluster synchronization in networks of oscillators with heterogenous Kuramoto dynamics, where multiple groups of oscillators with identical phases coexist in…
On the existence of a solution to a spectral estimation problem \emph{à la} Byrnes-Georgiou-Lindquist
Bin Zhu, Giacomo Baggio
A parametric spectral estimation problem in the style of Byrnes, Georgiou, and Lindquist was posed in \cite{FPZ-10}, but the existence of a solution was only proved in a special ca…

Giacomo Baggio, Augusto Ferrante, Rodolphe Sepulchre
The paper generalizes Thompson and Hilbert metric to the space of spectral densities. The resulting complete metric space has the differentiable structure of a Finsler manifold wit…
LTI Stochastic Processes: a Behavioral Perspective
Giacomo Baggio, Rodolphe Sepulchre
This paper revisits the definition of linear time-invariant (LTI) stochastic process within a behavioral systems framework. Building on [Willems, 2013], we derive a canonical repre…
