mlr_pipeops_nn_batch_norm3d: 3D Batch Normalization

In mlr3torch: Deep Learning with 'mlr3'

3D Batch Normalization

Description

Applies Batch Normalization for each channel across a batch of data.

nn_module

Calls torch::nn_batch_norm3d(). The parameter num_features is inferred as the second dimension of the input shape.

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

• eps :: numeric(1)
  A value added to the denominator for numerical stability. Default: 1e-5.

• momentum :: numeric(1)
  The value used for the running_mean and running_var computation. Can be set to NULL for cumulative moving average (i.e. simple average). Default: 0.1

• affine :: logical(1)
  a boolean value that when set to TRUE, this module has learnable affine parameters. Default: TRUE

• track_running_stats :: logical(1)
  a boolean value that when set to TRUE, this module tracks the running mean and variance, and when set to FALSE, this module does not track such statistics and always uses batch statistics in both training and eval modes. Default: TRUE
