# BNNS.ActivationFunction.gumbelMax(alpha:beta:)

An activation function that returns random numbers from the Gumbel distribution.

```
case gumbelMax(alpha: Float, beta: Float)
```

## Discussion

This constant defines an activation function that returns values using the following operation:

```c
 GumbleMax(X)_i = MAX(−log(−log(alpha*Uniform(0,1)+beta)+beta) + Xj) 
```
