This research aims to understand how reservoir topology influences prediction performance in nonlinear dynamical systems.
Analyzed four dynamical systems of varying complexity: Mackey-Glass, thermal convection flows, and shear flow models.
Evaluated five reservoir topologies with controlled connectivity patterns and edge weights.
Conducted direct and cross-prediction tasks to assess prediction performance.
Symmetric reservoir networks improved prediction accuracy for convection systems with fewer inputs than degrees of freedom.
Shear-flow model exhibited minimal sensitivity to reservoir topology due to chaotic dynamics.
Findings highlight the importance of network structure in learning complex dynamics.
