Conjugate gradient descent¶. The gradient descent algorithms above are toys not to be used on real problems. As can be seen from the above experiments, one of the problems of the simple gradient descent algorithms, is that it tends to oscillate across a valley, each time following the direction of the gradient, that makes it cross the valley. 13.

The conjugate gradient method is an algorithm for finding the nearest local minimum of a function of variables which presupposes that the gradient of the function can be computed. It uses conjugate directions instead of the local gradient for going downhill. If the vicinity of the minimum has the shape of a long, narrow valley, the minimum is reached in far fewer ... The conjugate gradient method is a mathematical technique that can be useful for the optimization of both linear and non-linear systems. This technique is generally used as an iterative algorithm, however, it can be used as a direct method, and it will produce a numerical solution. Div [{f 1, f 2, …, f n}, {x 1, x 2, …, x n}] is the trace of the gradient of f: Compute Div in a Euclidean coordinate chart c by transforming to and then back from Cartesian coordinates: The result is the same as directly computing Div [ f , { x 1 , … , x n } , c ] : Apply the conjugate gradient method to this problem from $\mathbf{x_0=0}$ and show that it converges in two iterations. Verify that there are just two independent vectors in the sequence $\mathbf{g_0,Gg_0,G^2g_0,\dots}$.
