Consider the two class classification task that consists of the following points:

Class $C_1$: [-1, -1], [-1, 1], [1, -1]

Class $C_2$: [1,1]

The decision boundary between the two classes $C_1$ and $C_2$ using single perception is given by:

  1. $x_1-x_2-0.5=0$
  2. $-x_1-x_2-0.5=0$
  3. $0.5(x_1+x_2)-1.5=0$
  4. $x_1+x_2-0.5=0$

It assumes a sign function, i.e try replacing x and y, the equation which classifies the dataset properly is the right answer.

e.g for case four.

-1 -1  -.5 = -2.5 since it turned out negative call it Class C1

-1+1 -.5=-.5 class C1

 1-1-.5=-.5 class C1

 and finally

1+1-.5-=1.5 since this is positive call it C2

 


Note: option D  is the only equation that classifies them properly hence the answer.
