| (1,1) (0,1) (1,0) (0,0) |
|
| R1
= 1/5, 4/5, 5/5, 0/5 |
|
| R2
= 1/5, 4/5, 2/5, 3/5 |
|
| R3
= 4/5, 1/5, 1/5, 4/5 |
|
| R4
= 2/5, 3/5, 4/5, 1/5 |

| New x = <0, 0, 1, 1> |

| S(1) = R1(0,1)*R2(0,1)*R3(1,1)*R4(1,1) = .205 |

| S(0) = R1(0,0)*R2(0,0)*R3(1,0)*R4(1,0) =

| S(1) > S(0),
so predict v = 1. |
