Conditional mean of inputs given noisy soft rounded values.
tfc.ops.soft_round_conditional_mean(
y, alpha
)
Computes g(z) = E[Y | s(Y) + U = z] where s is the soft-rounding function,
U is uniform between -0.5 and 0.5 and Y is considered uniform when truncated
to the interval [z-0.5, z+0.5].
This is described in Sec. 4.1. in the paper
