利用隐藏神经元解决异或问题的小型示例程序

#include <stdio.h>
#include <stdlib.h>

struct neuron {
    int w1;
    int w2;
    float b;
};

int phi(struct neuron *n, int i,int j) {
    float ret;
    ret = (float)(n->w1)*i + (float)(n->w2)*j + (float)(n->b);
    if (ret<0)
        return 0;
    else
        return 1;
}

int main() {
    int ret,k;
    int i[4] = {0,1,0,1};
    int j[4] = {0,0,1,1};
    struct neuron n1 = {1,1,-1.5};
    struct neuron n2 = {1,1,-0.5};
    struct neuron n3 = {-2,1,-0.5};
    for (k=0;k<4;k++) {
        ret = phi(&n3,phi(&n1,i[k],j[k]),phi(&n2,i[k],j[k]));//神经元的构成方式
        printf("(%d,%d),output is %d\n",i[k],j[k],ret);
    }
    return 1;
}
