WebDec 15, 2024 · If the input gradient is small, then the change in the output should be small too. Below is a naive implementation of input gradient regularization. The implementation is: Calculate the gradient of the … WebI Gradient? rJLOG S (w) = 1 n Xn i=1 y(i) ˙ w x(i) x(i) I Unlike in linear regression, there is no closed-form solution for wLOG S:= argmin w2Rd JLOG S (w) I But JLOG S (w) is convex and di erentiable! So we can do gradient descent and approach an optimal solution. 5/22
