pub fn from_sigmoid(
spec: &SigmoidSpec,

shape: (usize, usize),
target: &SpatialTarget,
) -> Result<SpatialProgram, SpatialReject>Expand description
y = sigmoid(x) — 1/(1 + e^-x), the reciprocal of the silu denominator. No new SFPU kind: Exp
and Recip already exist and the composition of the two IS the sigmoid.
