WebGradient Checking is slow! Approximating the gradient with ∂ J ∂ θ ≈ J (θ + ε) − J (θ − ε) 2 ε is computationally costly. For this reason, we don't run gradient checking at every iteration during training. Just a few times to check if the gradient is correct. Gradient Checking, at least as we've presented it, doesn't work with ...
