Which is the activation function of the Gelu?

Which is the activation function of the Gelu?

The Gaussian Error Linear Unit, or GELU, is an activation function. The GELU activation function is $xPhi (x)$, where $Phi (x)$ the standard Gaussian cumulative distribution function. The GELU nonlinearity weights inputs by their percentile, rather than gates inputs by their sign as in ReLUs ($xmathbf {1}_ {x>0}$).

What is the equation for Gelu in Bert?

I was going through BERT paper which uses GELU (Gaussian Error Linear Unit) which states equation as GELU(x) = xP(X ≤ x) = xΦ(x). which in turn is approximated to 0.5x(1 + tanh[√2 / π(x + 0.044715×3)]) Could you simplify the equation and explain how it has been approximated.

How does Gelu work with the RNN regularizer?

Both of the above methods together decide a neuron’s output. Yet, the two work independently from each other. GELU aims to combine them. Also, a new RNN regularizer called Zoneout stochastically multiplies the input by 1.

How to combine the C tionalities in Gelu?

GELU aims to combine them. Also, a new RNN regularizer called Zoneout stochastically multiplies the input by 1. We want to merge all 3 fun c tionalities by stochastically multiplying the input by 0 or 1 and getting the output value (of the activation function) deterministically.

Is there a new activation function called Gelu?

GELU activation. A new activation function called GELU… | by SG | Medium Activations like ReLU, ELU and PReLU have enabled faster and better convergence of Neural Networks than sigmoids. Also, Dropout regularizes the model by randomly multiplying a few activations by 0. Both of the above methods together decide a neuron’s output.
