Struct LayerNorm

Source

pub struct LayerNorm {
    pub n_features: usize,
    pub gamma: Vec<f64>,
    pub beta: Vec<f64>,
    pub epsilon: f64,
}

Expand description

Layer normalisation applied to each time step independently.

Normalises a feature vector of length n_features to zero mean and unit variance, then applies learnable scale (gamma) and bias (beta).

Fields§

§n_features: usize

Number of features.

§gamma: Vec<f64>

Learnable scale parameter.

§beta: Vec<f64>

Learnable shift parameter.

§epsilon: f64

Numerical stability constant.

Implementations§

Source §

impl LayerNorm

Source

pub fn new(n_features: usize) -> Self

Create a new layer norm with identity initialisation (gamma=1, beta=0).

Source

pub fn forward(&self, x: &[f64]) -> Vec<f64>
