Continuation-Based Optimizer Stability Map

Treat the optimizer-plus-network dynamics as a parameterized discrete dynamical system and continue its stationary points as learning rate, momentum, weight decay, or optimizer time constants vary. Detect the transition where a Jacobian eigenvalue crosses the unit circle, then use the computed boundary as an adaptive ceiling instead of discovering instability through failed training.

Envelope-Gradient Optimization Layer

When the training objective uses only the optimal value of a differentiable quadratic program, bypass the adjoint KKT solve entirely and differentiate the value with respect to neural predictions using the envelope theorem. This is especially suitable for decision-focused learning where the network predicts costs, loads, or constraints and the loss is the resulting optimal operating cost.
