A Factor Graph Approach to Scalable Multi-Output Gaussian Process Regression
Wouter W. L. Nuijten, Esther G. van Pelt, Albert Podusenko +2
Multi-output Gaussian process regression scales cubically in the number of observations times outputs, and dense kernel-matrix methods need bespoke handling whenever different outp…
Will a time-varying complex system be stable?
Francesco Ferraro, Christian Grilletta, Amos Maritan +2
Randomly-assembled dynamical systems are theoretically predicted to be unstable upon crossing a critical threshold of complexity, as first shown by May. Yet, empirical complex syst…
Synchronization and chaos in complex ecological communities with delayed interactions
Francesco Ferraro, Christian Grilletta, Emanuele Pigani +3
Explaining the wide range of dynamics observed in ecological communities is challenging due to the large number of species involved, the complex network of interactions among them,…
Exact solution of Dynamical Mean-Field Theory for a linear system with annealed disorder
Francesco Ferraro, Christian Grilletta, Amos Maritan +2
We investigate a disordered multi-dimensional linear system in which the interaction parameters vary stochastically in time with defined temporal correlations. We refer to this typ…
Generalized Lotka-Volterra Systems with Time Correlated Stochastic Interactions
Samir Suweis, Francesco Ferraro, Christian Grilletta +2
In this work, we explore the dynamics of species abundances within ecological communities using the Generalized Lotka-Volterra (GLV) model. At variance with previous approaches, we…
