# BNNSActivationFunctionClamp

An activation function that returns its input clamped to the specified range.

## Declaration

```occ
BNNSActivationFunctionClamp
```

## Discussion

Discussion This constant defines an activation function that returns values using the following operation: min(max(x, alpha), beta) Use alpha and beta to specify the clamping range: var activation = BNNSActivation(function: .clamp,                                  alpha: -5,                                  beta: 5) The following illustrates the output that the activation function generates from inputs in the range -10...10:
