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).

Now for the other direction, we can drop the requirement of simple connectedness, as if f is conservative, then it always holds that. ∀ ( x, y) ∈ Ω: ∂ 1 f 2 ( x, y) = ∂ 2 f 1 ( x, y). fisher park clearfield utah cameras
