Struct MseLoss 

pub struct MseLoss;

Calculate the mean squared error loss from the input logits and the targets.

Implementations

impl MseLoss

pub fn new() -> Self

Create the criterion.

pub fn forward<B: Backend>( &self, logits: Tensor<B, 2>, targets: Tensor<B, 2>, reduction: Reduction, ) -> Tensor<B, 1>

Compute the criterion on the input tensor.

Shapes

• logits: [batch_size, num_targets]
• targets: [batch_size, num_targets]

pub fn forward_no_reduction<const D: usize, B: Backend>( &self, logits: Tensor<B, D>, targets: Tensor<B, D>, ) -> Tensor<B, D>

Compute the criterion on the input tensor without reducing.
