In this homework you will code gradient descent and use it to find the minimizer of a function, i.e., to solve an optimization problem of the form arg min f(x) XERD Recall that given a function f(x) to be minimized, gradient descent can be summarized as follows (i) Select an initial point xo (ii) For every t > 0, repeat: until convergence, where > 0 is a step size (parameter). Implement gradient descent in your favorite coding language, and use it to identify the solution to arg min |Ax - b XER where 1 2 48 16 A-1 3 9 27 81 1 4 16 64 256 1 5 25 125 625 31 b = | 121 341 781 Deliver your code, solution, and choice of
