GELU
Activation function used in transformer feed-forward layers.
Visão geral
GELU multiplies its input by the probability that a standard normal is less than it, giving a smooth curve that is not monotonic and dips slightly below zero. It solves the problem that a rectifier has a hard corner at zero, which turns out to train slightly worse in deep transformers. It exists as the default activation in most current models, chosen empirically over ReLU.
