这是最简单的下降方法,我们也可以添加各种其它下降因素。比如可以把前面一次的偏导数大小与方向记着,与当前的偏导数大小与方向共同作用产生本次的移动方向与移动速度。 已经整理位于云盘中,资料整理/机器学习书籍/Neural Network and Deep Learning-中文版.pdf 已整理至公众号关键词回复:数据整理。

It turns out that we can devise learning algorithms which can automatically tune the weights and biases of a network of artificial neurons. This tuning happens in response to external stimuli, without direct intervention by a programmer. These learning algorithms enable us to use artificial neurons ...
The main part of the chapter is an introduction to one of the most widely used types of deep network: deep convolutional networks. We'll work through a detailed example - code and all - of using convolutional nets to solve the problem of classifying handwritten digits from the MNIST data se...
