In the lectures, we introduced Gradient Descent, an optimization method to find the minimum value of a function. In this problem we try to solve a fairly simple optimization problem: min f(x) = x2 TER That is, finding the minimum value of x2 over the real line. Of course you know it is when x = 0, but this time we do it with gradient descent. Recall that to perform gradient descent, you start at an arbitrary initial point xo,...
