Homework Backpropagation by Hand

In A Step by Step Backpropagation Example of Matt Mazur the updated weights took the fowling value

Some sources use a $($alpha$)$ to represent the learning rate, others use $?($eta$),$ and others even use e $($epsilon$).$

We can repeat this process to get the new weights $w_6{w}_7$ and $w_8$

$w_n^t=0\mathrm{.}408666186$

$u_3^t=0\mathrm{.}511301270$

$u_k^t=0\mathrm{.}561370121$

We can now update $w_1$

Repeating this for $w_2,w_3$ and $w_4$

$w_2^{+}=0\mathrm{.}19956143$

$w_3^{+}=0\mathrm{.}24975114$

$w_4^{+}=0\mathrm{.}29950229$

Repeat the weight update process again to get new weights in the second iteration if the input vector $\{0\mathrm{.}60\mathrm{.}2]$ is presented with an output vector of $0\mathrm{.}20\mathrm{.}98.$
