Consider the unit shown on Figure $1.$ Suppose that the weights corresponding to the three inputs have

the following values:

$w_1=,2$

$w_2=,-4$

$w_3=,1$

and the activation of the unit is given by the step$-$function:

$(v)=\{\begin{array}{ccc}1& if& v0\\ 0& \text{o}\text{t}\text{h}\text{e}\text{r}\text{w}\text{i}\text{s}\text{e}& \end{array}$

Calculate what will be the output value $y$ of the unit for each of the following input patterns:
