Please read the $$Chapter $4\mathrm{.}4$ Neural Network Demos.pdf $$ carefully before you start working on

this assignment.

$1.$ Task $1($handwritten$)$:

$$ Based on the problem description, and the instruction, please write down the

computation equation for the $3-$layer Neural Network.

$$ Please describe what loss function you should use here, what are they and what are

their functionality.

$$ Please draw the computational graph for the final loss computation, given the input,

and list the computations for forward propagation and backward propagation
