Leaky ReLU函数:z < 0时,a = max(0.01z, z);z > 0时,a = max(0,z)。 Why do you need non-linear activation functions? 假设我们使用的激活函数为线性激活函数,以恒等激活函数为例,进行说明。恒等激活函数,将输入的值进行线性计算之后直接作为该层的输出值。如果a[1]=z[1]=W[1]*x+b[1],a[...

As a powerful modelling method, piecewise linear neural networks (PWLNNs) have proven successful in various fields, most recently in deep learning. To apply PWLNN methods, both the representation and the learning have long been studied. In 1977, the canonical representation pioneered the works of...
In this chapter, the basic concepts of deep learning will be presented to provide a better understanding of these powerful and broadly used algorithms. The analysis is structured around the main components of deep learning architectures, focusing on convolutional neural networks and autoencoders....
For half a century, artificial intelligence research has attempted to reproduce the human qualities of abstraction and reasoning - creating computer systems that can learn new concepts from a minimal set of examples, in settings where humans find this easy. While specific neural networks are able to...
