A neural network, or artificial neural network, is a type of computing architecture that is based on a model of how a human brain functions — hence the name "neural." Neural networks are made up of a collection of processing units called "nodes." These nodes pass data to each other, j...

Examples of nonlinear activation functions include logistic sigmoid, Tanh, and ReLU functions.LAYERA layer is the highest-level building block in machine learning. The first, middle, and last layers of a neural network are called the input layer, hidden layer, and output layer respectively. The ...
PRML第5章介绍了神经网络neural network,是最近非常火的deep learning的基础,值得好好看一看。 第5章 Neural Networks 在第3章和第4章,我们已经学过线性的回归和分类模型,这些模型由固定的基函数(basis functions)的线性组合组成。这样的模型具有有用的解析和计算特性,但是因为维度灾难(the curse of dimensionality)...

In machine learning, an artificial neural network is an algorithm inspired from biological neural network and is used to estimate or approximate functions that depend on a large numb...
Beresteanu (2003) points out that each finite expansion, ψm,0(x),ψm,1(x) can potentially be based on a different set of functions [Beresteanu (2003), p. 9]. We now discuss the most commonly used functional forms in the neural network literature. 2.4.2 Squasher Functions The neuro...
