Composite Functions in Drive Activation Function for Neural Networks or Wavelet Networks or Wavenetsunrestricted/ETD.pdf
Panel (a) shows an activation function in neural networks and (b) displays typical activation functions. (6.2)sigmoid(x)=1/(1+e−x), (6.3)ReLU(x)=max(0,x), (6.4)tanh(x)=21+e−2x−1. The sigmoid used to be a frequent activation function but ReLU has recently been ...

A Survey on Activation Functions and their relation with Xavier and He Normal Initialization 来自 arXiv.org 喜欢 0 阅读量: 124 作者: L Datta 摘要: In artificial neural network, the activation function and the weight initialization method play important roles in training and performance of a ...
This state of affairs underscores the importance of theoretically understanding the impact of activation functions on training. In the present paper, we provide theoretical results about the effect of activation function on the training of highly overparametrized 2-layer ne...
Though a wide variety of nonlinear activation functions have been proposed foruse in artif i cial neural networks, a detailed understanding of their role in determining the expressivepower of a network has not emerged. Here, we study how activation functions af f ect the storagecapacity of tree...

Activation functions. Different non-linear activation functions are frequently used in deep neural networks. (16.12)tanh(x)=e2x−1e2x+1. However, an issue with the Sigmoid and tanh functions is that they saturate the outputs within a bounded range, such as 0 to 1 for the former and ...
