Collective-Mode De-Gennes Optimizer
Replace a single global learning rate with mode-dependent rates determined by the static correlation structure of recent parameter updates or hidden-state updates. Correlated modes are treated as collective diffusive modes: their effective relaxation rate is reduced in proportion to their structure-factor amplitude, so the optimizer accelerates weakly correlated modes while damping collective slow modes. The method also supplies a diagnostic for when the Markovian approximation is invalid and…
