-* Familiar (toy) example: Optimizing selection "cut" for an analysis.<br>
-Place discriminate selection cut on observable $x$ to maximize significance.
-* Traditionally, step along values in $x$ and calculate significance at each selection. Keep maximum.
-* Need differentiable analogue to non-differentiable "cut".<br>
-Weight events using activation function of sigmoid

-* Most importantly though, with the differentiable model we have access to the gradient $\partial_{x} f(x)$
-* So can find the maximum significance at the point where the gradient of the significance is zero $\partial_{x} f(x) = 0$
-* With a simple gradient descent algorithm can easily automate the significance optimization
