Did you know?
In the context of artificial neural networks, the rectifier or ReLU (rectified linear unit) activation function is an activation function defined as the positive part of its argument: where x is the input to a neuron. This is also known as a ramp function and is analogous to half-wave rectification in electrical engineering. … Visa mer • Sparse activation: For example, in a randomly initialized network, only about 50% of hidden units are activated (have a non-zero output). • Better gradient propagation: Fewer vanishing gradient problems compared … Visa mer • Non-differentiable at zero; however, it is differentiable anywhere else, and the value of the derivative at zero can be arbitrarily chosen to be 0 or 1. Visa mer • Softmax function • Sigmoid function • Tobit model Visa mer Piecewise-linear variants Leaky ReLU Leaky ReLUs allow a small, positive gradient when the unit is not active.
