New neural algorithm approximates nonlinear system modes

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new data-driven algorithm using neural networks to approximate the dominant modes of nonlinear dynamical systems. This method leverages a power-iteration scheme to directly learn these modes, avoiding the curse of dimensionality associated with complex function templates. The approach is entirely data-driven, requiring only sampled state transitions, and offers theoretical guarantees for convergence. Numerical experiments show it achieves accurate and smooth approximations, outperforming traditional techniques like extended dynamic mode decomposition. AI

IMPACT This method could enable more simplified control and analysis of nonlinear dynamical systems by enabling linear approximations in a lifted space.
