制作一个1*2*2的网络,r是一个随机数取值方法是
Random rand1 =new Random();
int ti1=rand1.nextInt(99)+1;
r=sigmoid( (double)ti1/100);
Random rand2 =new Random();
int ti2=rand2.nextInt(99)+1;
r1=sigmoid( (double)ti2/100);

分别向两边输入r和1+r1。并让1*2*2部分的权重共享,前面大量实验表明这种效果相当于将两个弹性系数为k1,k2的弹簧并联成一个弹性系数为k的弹簧,并且让k1=k2=k/2的过程。
将这个网络简写成
d2(r,1+r1)-1-2-2-(2*k),k∈{0,1}

比如最后一组数据的意思当进样1+r1>=1.39的时候网络全部判断为对的,正确率为62.4%,对应的s值为99.将1+r1画成图

将s=奇数的画成图

将s=偶数的画成图。

也就是图1是由图2和图3合成的。
观察当s=奇数的数据

将1+r1画成图

1+r1的数据与准确率高度相关,可以明显的看到当s增加后1+r1变得平稳了,也就表明随着s的增加网络
d2(r,1+r1)-1-2-2-(2*k),k∈{0,1}
的收敛准确率变得稳定,并最终当s无限大近似随机的时候将趋于1个定值。
观察当s=偶数的图像

当s=奇数的图像

可以看到无论当s=偶数或者s=奇数1+r1的图都平稳的多,可以将s=奇数的图像拟合成直线

将准确率画成图

可以看到当s增加以后当s=奇数的1+r1曲线与实测准确率重合度大幅增加。可以推测当s趋于无穷大的时候s=奇数的1+r1曲线将与当r随机取值时的准确率相等,

0.42365:0.577108 和468与595已经很接近。当正确的个数为468时s是偶数,当正确个数是595时s为奇数,也就是网络
d2(r,1+r1)-1-2-2-(2*k),k∈{0,1}
左侧对奇数敏感,右侧对偶数敏感,并且对这个网络来说奇数和偶数的重要性不是1:1的。这个网络的准确率与训练集是奇数个还是偶数个是高度相关的。可以用当s=奇数的1+r1对s的曲线高度拟合网络的准确率。这个网络的准确率侧面反映了这个网络对奇数或者偶数个训练集的敏感程度,当s=无穷大的时候这个网络对奇数和偶数的敏感度比值57.7108:42.365.
