mlr_pipeops_nn_sigmoid function

Sigmoid Activation Function

Applies element-wise $Sigmoid(x_i) = \frac{1}{1 + exp(-x_i)}$

nn_module

Calls torch::nn_sigmoid() when trained.

Parameters

No parameters.

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_sigmoid")
pipeop
# The available parameters
pipeop$param_set
