Graduado em: Big Data e Inteligência Analítica pela PUCPR Minha … In biologically inspired neural networks, the activation function is usually an abstraction representing the rate of action potential firing in the cell. [3] In its simplest form, this function is binary —that is, either the neuron is firing or not. The function looks like , where is the Heaviside step function . 查看更多內容 In artificial neural networks, the activation function of a node defines the output of that node given an input or set of inputs. A standard integrated circuit can be seen as a digital network of activation functions that can be "ON" (1) … 查看更多內容 There are numerous activation functions. Hinton et al.'s seminal 2012 paper on automatic speech recognition uses a logistic sigmoid activation function. The seminal 2012 AlexNet computer vision architecture uses the ReLU activation function, as did … 查看更多內容 The most common activation functions can be divided in three categories: ridge functions, radial functions and fold functions. An activation function $${\displaystyle f}$$ is saturating if $${\displaystyle \lim _{ v \to \infty } \nabla f(v) =0}$$. It is nonsaturating if it is not … 查看更多內容 • Logistic function • Rectifier (neural networks) • Stability (learning theory) • Softmax function 查看更多內容
