Try it again. So, sure enough, changing the bias changed the price, and even changed it in the right direction.
我们再来运行一下,好了,很明显,这个偏向值改变了价格,而且方向也是对的。
All right. If the derivative is small, it's not changing, maybe want to take a larger step, but let's not worry about that all right?
好,如果导数很小的话,函数就基本没什么变化,可能我们就想把步子迈大一点儿了,但是别为这个担心?
Your compressing it really fast, all right, so you're changing the pressure.
你把它压缩的非常快,好的,那么你改变了压力。
I'm not taking a cut on that either, all right, there's no money changing hands.
我不会从中得到提成,这不是推销
And remind you that inside of here, I'd better be changing the variable. All right, if that variable that's counting is not changing I'm going to be stuck in an infinite loop, so I ought to that, right, expect somewhere in there, a change of that variable. All right?
我最好改变了计数器的变量值,好,如果计数的变量没有变化的话,我就会被卡在一个无限循环里面,因此我应该【不可闻的声音】,对,在这里的某个地方,改变下计数器的变量,对不对?我要做的最后一件事情就是?
b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?
好,在这个例子里我会用,因为b是一直在变的东西,但是也可能是如下情况:,如果输入是数组的话,变化的就是数组的元素数,如果输入是字符串的话,变化的就是字符串的长度,如果是integer的话,可能就是这个数的大小,对不对?
