第十二章SVM笔记中的几处错误 #30
Comments
谢谢,我先看看 |
P179:倒数第二段中,反之,如果y = 0,我们观察一下,函数cost0(z),它只有在z <= 1的区间里有函数值为0。不是z <= 1,而应该是z <= -1。 |
P187:第二段,这个θTx(i) > = 1 或者θTx(i) < -1的,约束是可以被p(i).x >= 1这个约束所代替的。不是p(i).x >=1而应该是p(i).||θ||。 |
P190:第四段中,得到hθ(x) = f1 + f2 + … + fn,应该是hθ(x) = (theta1)f1 + (theta2)f2 + ... + (thetan)fn。已经修改 |
都已经更新到新版本笔记 |
👍👍👍 |

最近在学习SVM,把笔记V5.32中SVM这一章的内容通读了一遍,发现了下面几处小错误,希望作者有时间能够修复这些错误。
P174
:第二段,我们同样可以看到,当z增大时,也就是相当于θTx增大时,z对应的值会变得非常小。
不是z
的值变得非常小,而应该是代价函数的值
变得非常小。P178
:倒数第二段中,反之,如果y = 0,我们观察一下,函数cost0(z),它只有在z <= 1的区间里有函数值为0
。不是z <= 1
,而应该是z <= -1
。P186
:第二段,这个θTx(i) > = 1 或者θTx(i) < -1的,约束是可以被p(i).x >= 1这个约束所代替的
。不是p(i).x >=1
而应该是p(i).||θ||
。P190
:第四段中,得到hθ(x) = f1 + f2 + … + fn
,应该是hθ(x) = (theta1)f1 + (theta2)f2 + ... + (thetan)fn
