3D Convolution

Source: R/PipeOpTorchConv.R
mlr_pipeops_nn_conv3d.Rd

Applies a 3D convolution over an input image composed of several input planes.

nn_module

Calls torch::nn_conv3d() when trained. The paramter in_channels is inferred from the second dimension of the input tensor.

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().

Parameters

  • out_channels :: integer(1)
    Number of channels produced by the convolution.

  • kernel_size :: integer()
    Size of the convolving kernel.

  • stride :: integer()
    Stride of the convolution. The default is 1.

  • padding :: integer()
    ‘dilation * (kernel_size - 1) - padding’ zero-padding will be added to both sides of the input. Default: 0.

  • groups :: integer()
    Number of blocked connections from input channels to output channels. Default: 1

  • bias :: logical(1)
    If ‘TRUE’, adds a learnable bias to the output. Default: ‘TRUE’.

  • dilation :: integer()
    Spacing between kernel elements. Default: 1.

  • padding_mode :: character(1)
    The padding mode. One of "zeros", "reflect", "replicate", or "circular". Default is "zeros".
