Sparse Interactions Reshape Stability in Random Lotka-Volterra Dynamics
Mattia Tarabolo, Luca Dall'Asta, Roberto Mulet
Classical approaches to ecological stability rely on fully connected interaction models, yet real ecosystems are sparse and structured--a feature that qualitatively reshapes their…

Gaussian approximation of dynamic cavity equations for linearly-coupled stochastic dynamics
Mattia Tarabolo, Luca Dall'Asta
Stochastic dynamics on sparse graphs and disordered systems often lead to complex behaviors characterized by heterogeneity in time and spatial scales, slow relaxation, localization…

Small-Coupling Dynamic Cavity: a Bayesian mean-field framework for epidemic inference
Alfredo Braunstein, Giovanni Catania, Luca Dall'Asta +3
We present the Small-Coupling Dynamic Cavity (SCDC) method, a novel generalized mean-field approximation for epidemic inference and risk assessment within a fully Bayesian framewor…
