Struct burn_core::nn::Linear

pub struct Linear<B: Backend> { /* private fields */ }

Applies a linear transformation to the input tensor:

O = IW + b

Params

• weight: Matrix of shape [d_input, d_output] initialized from a uniform distribution: U(-k, k), where k = sqrt(1 / d_input)

• bias (optional): Vector of size d_output initialized from a uniform distribution: U(-k, k), where k = sqrt(1 / d_input)

Implementations

impl<B: Backend> Linear<B>

pub fn forward<const D: usize>(&self, input: Tensor<B, D>) -> Tensor<B, D>

Applies the forward pass on the input tensor.

Shapes

• input: [..., any, d_input]
• output: [..., any, d_output]
