In this tutorial we aim to comprehensively explain how Gaussian Error Linear Unit, GELU activation works.

Can we combine regularization and activation functions? In 2016 a paper from authors Dan Hendrycks and Kevin Gimpel came out. Since then, the paper now has been updated 4 times. The authors introduced a new activation function, the Gaussian Error Linear Unit, GELU.

The motivation behind GELU activation is to bridge stochastic regularizers, such as dropout, with non-linearities, i.e., activation functions.

Dropout regularization stochastically multiplies a neuron’s inputs with 0, randomly… Read the full blog for free on Medium.
