另一半是非线性的，所以它被称为分段线性函数（piecewise linear function ）。3. 如何实现ReLU 我们可以很容易地在 Python 中实现ReLU激活函数。# rectified linear function def rectified(x): return max(0.0, x)我们希望任何正值都能不变地返回，而0.0或负值的输入值

Artificial neural network (ANN) is one of the technologies used for emerging real-world problems. Activation functions (AF) are used in deep learning architectures to make decisions in the hidden and output layers. An AF influences the dynamics of training and performance of an ANN. This paper...
如果我的推导没错的话,那么激活函数的形式就应该是 1.67653251702 * x * sigmoid(x)。 jbmlres:在《Sigmoid-Weighted Linear Units for Neural Network Function Approximation in Reinforcement Learning》这篇论文中,所使用的激活函数难道不是类似的结构吗? inkognit:该激活函数和 Facebook 提出的门控线性单元(Gate...
