Implementations

impl LayerNorm

pub fn new( dimensions: impl Into<i32>, ) -> Result<Self, <<Self as Buildable>::Builder as Builder<Self>>::Error>

Creates a new instance of LayerNorm.

impl LayerNorm

pub const DEFAULT_EPS: f32 = 1e-5

Default value for eps.

pub const DEFAULT_AFFINE: bool = true

Enable trainable weight and bias by default.

Trait Implementations

impl Buildable for LayerNorm

type Builder = LayerNormBuilder

The builder type for this buildable type

impl Builder<LayerNorm> for LayerNormBuilder

type Error = Exception

Error with building

fn build(self) -> Result<LayerNorm, Self::Error>

Build the type

impl Clone for LayerNorm

fn clone(&self) -> LayerNorm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LayerNorm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Module<&Array> for LayerNorm

type Error = Exception

Error type for the module.

type Output = Array

Output type of the module.

fn forward(&mut self, x: &Array) -> Result<Array, Self::Error>

Forward pass of the module.

fn training_mode(&mut self, _mode: bool)
