计算双输入单输出的感知器网络的网络权值。参考输入输出为：

x1(1)=1 x2(1)=1 d(1)=1；

x1(2)=-0.5 x2(2)=-1 d(2)=-1；

x1(3)=3 x2(3)=1 d(3)=1；

x1(4)=-2 x2(4)=-1 d(4)=-1；-Calculation of the dual-input single-output perceptron network weights. Reference input and output:

  x1 (1) = 1 x2 (1) = 1 d (1) = 1

  x1 (2) =-0.5 x2 (2) =-1 d (2) =-1

  x1 (3) = 3 x2 (3) = 1 d (3) = 1

  x1 (4) =-2 x2 (4) =-1 d (4) =-1
