Question 1: Single choice

You compute integrated gradients with a Riemann sum of $m = 20$ steps. The attributions add up to 0.62, but $F(x) - F(x')$ is 0.87. What should you do?

Increase $m$ until the sum is close to $F(x) - F(x')$ 1
Rescale all attributions by the same factor so that they add up to 0.872
Nothing, since integrated gradients need not add up to $F(x) - F(x')$ 3
Switch to the plain gradient at $x$ , which needs no integral at all4
