20分钟搞懂神经网络BP算法

在学习深度学习过程中，无意间发现一篇介绍BP算法的文章，感觉非常直观，容易理解。这篇文章的最大亮点是：不像其他介绍BP算法的文章，用一堆数据符号和公式来推导。文中通过使用一条具体的样本数据，为我们展示了模型训练中的参数迭代计算过程，为我们理解BP算法提供了很直观的理解视角；其次，作者也给出了使用py...

为啥神经网络里的BP算法花了那么久才被发明?

Roseblatt在五十年代就提出了感知机, 又过了将近30年, 多层神经网络的BP算法才得以普及。而事实上这不过是微积分中链式法则的简单应用而已, 为什么要花这么久呢？ bengio在quora上这样回答道：很多看似显而易见的想法只有在事后才变得显而易见。在控制论中, 很早就开始应用链式反则...
