Batch normalization — mlx_batch_norm • Rmlx

Normalizes inputs across the batch dimension.

Usage

mlx_batch_norm(
  num_features,
  eps = 1e-05,
  momentum = 0.1,
  device = mlx_default_device()
)

Arguments

num_features: Number of feature channels.
eps: Small constant for numerical stability (default: 1e-5).
momentum: Momentum for running statistics (default: 0.1).
device: Execution target: supply "gpu", "cpu", or an mlx_stream created via mlx_new_stream(). Default: mlx_default_device().

Value

An mlx_module applying batch normalization.
