Predictive Lyapunov Switched Optimizer
Replace a single optimizer update rule by a finite set of update modes, such as conservative SGD, momentum SGD, high-step SGD, and Adam-like preconditioned descent. Because the selected mode is applied with a one-step delay, score every candidate using a nominal predictor and choose the mode with the greatest certified decrease of a phase-dependent Lyapunov function around a short periodic optimizer orbit. This creates a controlled limit cycle in parameter or loss-state space, allowing stable…
