Struct RmsNormGated 

pub struct RmsNormGated<B: Backend> {
    pub gamma: Param<Tensor<B, 1>>,
    pub norm_before_gate: bool,
}

Applies Gated Rms Normalization over an input tensor along the last dimension.

• If norm_before_gate=true: Y = (X / sqrt(mean(X^2) + eps) * gamma) * SiLU(z)
• If norm_before_gate=false: Y = (X * SiLU(z)) / sqrt(mean((X * SiLU(z))^2) + eps) * gamma

Where:

• X is the input tensor
• Y is the output tensor
• z is the gating tensor
• gamma is the learnable weight
• mean is the mean operation
• eps is a small value to avoid division by zero.

Should be created using the RmsNormGatedConfig configuration.

Fields

gamma: Param<Tensor<B, 1>>

The learnable parameter to scale the normalized tensor.

norm_before_gate: bool

Whether to normalize before applying the gating.
