$(1)$ Determine the weight matrices $U^1,U^2,U^3,U^4$ and

write them as Equation $(4\mathrm{.}1).$

$(2)$ Determine output o when $x=(1,0{)}^T$ is entered. Use

logistic sigmoid as the activation function.

$(3)$ Determine output o when $x=(1,0{)}^T$ is entered. Use

ReLU as the activation function.
