mlr_pipeops_nn_elu function

ELU Activation Function

Applies element-wise, [REMOVE_ME]$ELU(x) = max(0,x) + min(0, \alpha * (exp(x) - 1)) [REMOVE_ME_2]$.

Description

Applies element-wise,

$$ELU(x) = max(0,x) + min(0, \alpha * (exp(x) - 1))$$

.

nn_module

Calls torch::nn_elu() when trained.

Parameters

• alpha :: numeric(1)

  The alpha value for the ELU formulation. Default: 1.0

• inplace :: logical(1)

  Whether to do the operation in-place. Default: FALSE.

Input and Output Channels

One input channel called "input" and one output channel called "output". For an explanation see PipeOpTorch.

State

The state is the value calculated by the public method $shapes_out().

Examples

# Construct the PipeOp
pipeop = po("nn_elu")
pipeop
# The available parameters
pipeop$param_set
