Web26 Feb 2024 · Nitpick: tanh is also a sigmoid function. Any function with a S shape is a sigmoid. What you guys are calling sigmoid is the logistic function. The reason why the logistic function is more popular is historical reasons. It has been used for a longer time by statisticians. Besides, some feel that it is more biologically plausible. WebA rectified linear unit has the output $0$ if its input is less than or equal to $0$, otherwise, its output is equal to its input.This activation function is also more biologically accurate.It has been widely used in convolutional neural networks.It is also superior to the sigmoid and $\tanh$ activation function, as it does not suffer from the vanishing gradient problem.
