WebThe backward function of the basically takes the the incoming gradient from the further layers as the input. This is basically $\frac{\partial{L}}{\partial{d}}$ coming along the edge leading from L to d. This gradient is also the gradient of L w.r.t to d and is stored in grad attribute of the d. It can be accessed by calling d.grad. WebJun 13, 2016 · In particular, gradient flow is a descent method, which means it always decreases the objective function: d dt f(Xt) = ∇f(Xt), ˙Xt = − ‖∇f(Xt)‖2 ≤ 0. This is a natural property for optimization: Since our goal is to minimize f, it makes sense to decrease f as much as possible at each time. chiropractic today https://scrsav.com
