Layer normalization — mlx_layer_norm • Rmlx

Normalizes inputs across the feature dimension.

Usage

mlx_layer_norm(normalized_shape, eps = 1e-05, device = mlx_default_device())

Arguments

normalized_shape: Size of the feature dimension to normalize.
eps: Small constant for numerical stability (default: 1e-5).
device: Execution target: supply "gpu", "cpu", or an mlx_stream created via mlx_new_stream(). Default: mlx_default_device().

Value

An mlx_module applying layer normalization.
