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...

Introduction to Neural Network Tutorial Introduction: What are Neural Networks? Neural Networks are a form of computing which has its beginnings in the 40s, when people started thinking human brain as a computer. One of them was Alan Turing, one of the most famous computer scientist and ...
就不会出现在计算图中。从这个角度来说,一个CGP网络可以编码由简单到复杂 的近乎无穷种模型。一个具体的示例如下(来自Miller教授的PPSN 2014 Tutorial): 一个简单的CGP示例:注意图中节点6并未使用 CGP中的进化 当明确CGP中的个体表示后,剩下的问题就是如何进化每个个体,即通过随机的修改与有倾向性的选择,使整个...
