In the context of artificial neural networks, the rectifier is an activation function defined as

Noisy ReLUs[edit]
Rectified linear units can be extended to include Gaussian noise, making them noisy ReLUs, giving[3]
Noisy ReLUs have been used with some success in restricted Boltzmann machines for computer vision tasks.[3]

本文介绍了在人工神经网络中常用的激活函数——整流线性单元(ReLu)及其实现变种NoisyReLu。NoisyReLu通过引入高斯噪声改进了基本的ReLu函数,该变种被成功应用于受限玻尔兹曼机中解决计算机视觉任务。
