# 递归神经网络不可思议的有效性（上）

### 递归神经网络

RNN计算。那么这些是如何工作的呢？主要是，RNNs有一个非常简洁的API：它们将向量x作为输入，然后输出结果向量y.然而，关键的是这个输出向量的内容不仅受到前一次输入数据的影响，而且还会受整个历史输入数据的影响。这个API编写成了一个类，它由一个step方法构成：

```rnn = RNN()
y = rnn.step(x) # x is an input vector, y is the RNN's output vector```

RNN类有一些内部的状态，会在每一次调用 step方法的时候进行更新。最简单的情况是，这个状态由单个隐藏向量h构成。下面是Vanilla RNN中对step方法的一种实现：

```class RNN:
# ...
def step(self, x):
# update the hidden state
self.h = np.tanh(np.dot(self.W_hh, self.h) + np.dot(self.W_xh, x))
# compute the output vector
y = np.dot(self.W_hy, self.h)
return y```

```y1 = rnn1.step(x)
y = rnn2.step(y1)```

"The surprised in investors weren't going to raise money. I'm not the company with the time there are all interesting quickly, don't have to get off the same programmers. There's a super-angel round fundraising, why do you can do. If you have a different physical investment are become in people who reduced in a startup with the way to argument the acquirer could see them just that you're also the founders will part of users' affords that and an alternation to the idea. [2] Don't work at first member to see the way kids will seem in advance of a bad successful startup. And if you have to act the big company too."

"is that they were all the same thing that was a startup is that they were all the same thing that was a startup is that they were all the same thing that was a startup is that they were all the same"

```PANDARUS:
Alas, I think he shall be come approached and the day
When little srain would be attain'd into being never fed,
And who is but a chain and subjects of his death,
I should not sleep.

Second Senator:
They are away this miseries, produced upon my soul,
Breaking and strongly should be buried, when I perish
The earth and thoughts of many states.

DUKE VINCENTIO:
Well, your wit is in the care of side and that.

Second Lord:
They would be ruled after this chamber, and
my fair nues begun out of the fact, to be conveyed,
Whose noble souls I'll have the heart of the wars.

Clown:
Come, sir, I will make did behold your worship.

VIOLA:
I'll drink it.```

```VIOLA:
Why, Salisbury must find his flesh and thought
That which I am not aps, not a man and in fire,
To show the reining of the raven and the wars
To grace my hand reproach within, and not a fair are hand,
That Caesar and my goodly father's world;
When I was heaven of presence and our fleets,
We spare with hours, but cut thy council I am great,
Murdered and by thy master's ready there
My power to give thee but so much as hell:
Some service in the noble bondman here,
Would show him to her wine.

KING LEAR:
O, if you were a feeble sight, the courtesy of your law,
Your sight and several breath, will wear the gods
With his heads, and my hands are wonder'd at the deeds,
