DNN的背景
DNN,deep neural network,近几年机器学习算法中崛起的旗舰方法,作为分类精度最高、处理高维大数据的算法,挽救了机器学习在半个世纪里发展缓慢的颓势,也为人工智能新领域的拓展起着重要作用,来看看最近一些IT巨头在深度学习领域中的开展的工作。2012年,《纽约时报》报道的google Brian项目,引起广泛关注,这个项目由机器学习领域大师级人物吴恩达和大规模计算机系...

Learning前面,我们介绍了神经网络的构成,数据的预处理,权值的初始化等等。这一讲,我们将要介绍神经网络参数学习的过程。Gradient Checks梯度的运算,在理论上是简单的,但是在实际的应用中,却非常容易出错,梯度的运算常见的有如下两种形式:形式一:
df(x)dx=f(x+h)?f(x)h
\frac{df(x)}{dx}=\frac{f(x+h)-f(x)}{h}
hh是一个很小...
