GLU Activation Function

Source: R/PipeOpTorchActivation.R
mlr_pipeops_nn_glu.Rd

The gated linear unit. Computes:

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

  • dim :: integer(1)
    Dimension on which to split the input. Default: -1

Internals

Calls torch::nn_glu() when trained.
