Structure Over Nonlinearity: Explicit Interaction Architectures for Dynamical Learning
Researchers have proposed a new paradigm for learning dynamical systems that prioritizes explicit structure over generic nonlinearities. This approach utilizes wave-inspired interaction structures with internal states, creating causal organizations that avoid algebraic loops and allow for explicit model evaluation. Stacking these units leads to layered dynamical architectures with emergent hierarchical behavior, demonstrating improved representation quality and generalization on system identification tasks, even with limited optimization.
