TensorFlow implements a large number of pooling layers and a complete list is available online. ([https://www.tensorflow.org/api_guides/python/nn#Pooling](https://www.tensorflow.org/api_guides/python/nn#Pooling)) In short, all the pooling operations are nothing more than a summary operation on a given region.

For the sake of simplicity, we will use the framework TFLearn ([http://tflearn.org/](http://tflearn.org/)), which runs on top of TensorFlow. This example is part of the standard distribution and it is available at [https://github.com/tflearn/tflearn/blob/master/examples/nlp/lstm_generator_shakespeare.py](https://github.com/tflearn/tflearn/blob/master/examples/nlp/lstm_generator_shakespeare.py) . The model developed one is an RNN character-level language model where the sequences considered are sequences of characters and not words.
在本食谱中，我们将学习如何使用 RNN 预测未来的比特币价值。 关键思想是，过去观察到的值的时间顺序可以很好地预测未来的值。 对于此食谱，我们将使用 MIT 许可下的[这个页面](https://github.com/guillaume-chevalier/seq2seq-signal-prediction)上提供的代码。 给定时间间隔的比特币值通过 API 从[这里](https://www.coindesk.com/api/)下载。 这是 API 文档的一部分：
