The term in the exponent of $f(x,y)$ can be written as $$\begin{split}-\frac 18\left[4x^2+8x(y+3)+6(y+3)^2\right] &= -\frac 12 \left[x^2+2x(y+3)+\frac 32(y+3)^2\right]\\ &=-\frac 12\begin{... • 10.1k 1 vote Accepted ### Mean value of the derivation ReLU function with Normal Distribution Because we have$$\int_{-\infty}^\infty relu’(x)f(x)dx=\int_{-\infty}^\infty I(x>0)N(0,\sigma^2)dx=\int_0^\infty N(0,\sigma^2)dx=\frac12 the answer is $\frac12$.
