Webb22 okt. 2024 · Rectified Linear Unit is an activation function used in nearly all modern neural network architectures. It’s defined as max (0, x). At first glance it might look that … 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.
