Visualizations of the cost function over iterations provide insight into how the model learns ... by taking a deeper dive into model optimization and hyperparameter experimentation. Grasping the core ...

we develop a stochastic gradient descent scheme of the Kiefer–Wolfowitz type that applies over a single run of the state evolution. At each iteration, the proposed scheme computes an estimate of the ...

In the present work no utilization is made of the adjoint variables. The gradient is calculated by determining the response of the cost function to approximately impulsive control perturbations, ...
