mlr_pipeops_nn_selu {mlr3torch}R Documentation

SELU Activation Function

Description

Applies element-wise,

SELU(x) = scale * (max(0,x) + min(0, \alpha * (exp(x) - 1)))

, with \alpha=1.6732632423543772848170429916717 and scale=1.0507009873554804934193349852946.

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()⁠.

Credit

Parameters

Internals

Calls torch::nn_selu() when trained.
