WebGood that you've implemented the gradient check. Go back to `backward_propagation` and try to find/correct the errors * (Hint: check dW2 and db1)*. Rerun the gradient check … WebTo do so, I wrote the gradient checking procedure, calculating the analytical gradients and comparing them with the gradients from backpropagation. The point is that, even if the backpropagation algorithm seems correct to me, the difference between the gradients is always high (around 0.8, instead of the classic 1e-7). Layer class.
