This class implements a layer that calculates the `erf` activation function for each element of a single input.

## Settings

There are no settings for this layer.

## Trainable parameters

There are no trainable parameters for this layer.

## Inputs

There is only one input, which accepts a data blob of arbitrary size.

## Outputs

There is only one output of the same size as the input. Each element contains the value of the activation function on the corresponding element of the input.
