本文翻译自RECURRENT NEURAL NETWORKS TUTORIAL, PART 2 – IMPLEMENTING A RNN WITH PYTHON, NUMPY AND THEANO。 github地址 在这篇博文中,我们将会使用Python从头开始实现一个循环神经网络,并且利用Theano(一个在GPU上执行操作的库)优化原始的实现。所有的代码可以在github上获得。我将会跳过一些不影响理解循环神经网络...
This tutorial will run through the coding up of a simpleneural network(NN) in Python. We’re not going to use any fancy packages (though they obviously have their advantages in tools, speed, efficiency…) we’re only going to use numpy! 本教程将通过在Python中对一个简单的神经网络(NN)进行...

接下来第二部,要把之前推倒的公式,用python表现出来,很幸运numpy有太多强大的功能了,把tutorial的作者源码贴出来,以便有一个良好的对比: 对应的颜色 对应的一块儿代码对应的函数. 然后接着完成hidden layer到input layer的反向modify Boom! Three-layer nerual network has been accomplished!
I'm a novice programmer in Python and new to Deep Learning. Was reading your example of the XOR with one hidden layer and backpropagation seen in:https://www.bogotobogo.com/python/python_Neural_Networks_Backpropagation_for_XOR_using_one_hidden_layer.php...
In this simple neural network Python tutorial, we’ll employ the Sigmoid activation function. There are several types of neural networks. In this project, we are going to create the feed-forward or perception neural networks. This type of ANN relays data directly from the front to the back....
