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。
确实如此,修改了,这里是吴恩达老师讲课时候口误

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||。
已经修改

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
