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…
Unraveling the temporal dependence of ecological interaction measures
Javier Aguilar, Samir Suweis, Amos Maritan +1
Identifying the network of species interactions is a fundamental step toward understanding ecosystem stability and biodiversity. However, the interpretability of empirical interact…
Habitat heterogeneity and dispersal network structure as drivers of metacommunity dynamics
Davide Bernardi, Alice Doimo, Giorgio Nicoletti +5
Spatial structure and species interactions jointly shape the dynamics and biodiversity of ecological systems, yet most theoretical models either neglect spatial heterogeneity or sa…
Dispersal diversity buffers species vulnerability to local extinction
Davide Bernardi, Giorgio Nicoletti, Prajwal Padmanabha +5
Predicting species persistence within ecological communities is a fundamental challenge for both empirical and theoretical ecology. Existing methods span from mechanistic models, w…
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…
Topological Origin of the Diversity of Timescales in Recurrent Neural Circuits
Marco Zenari, Luca Taffarello, Luca Mazzucato +2
Structural and functional heterogeneity are hallmarks of cortical circuits, from broad degree distributions in the mouse connectome to diverse intrinsic neuronal timescales. Yet a…
