Optimization Welcome to the optimization's programming assignment of the hyper-parameters tuning specialization. There are many different optimization algorithms you could be using to get you to the minimal cost. Similarly, there are many different p
1. Optimization Methods Gradient descent goes "downhill" on a cost function \(J\). Think of it as trying to do this: **Figure 1** : **Minimizing the cost is like finding the lowest point in a hilly landscape** At each step of the training, you u
