Struct GaussianNllLoss

pub struct GaussianNllLoss {
    pub full: bool,
    pub eps: f32,
    pub reduction: LossReduction,
}

Compute the negative log likelihood loss for a Gaussian distribution.

Fields

full: bool

Whether to include the constant term in the loss calculation. Default to GaussianNllLoss::DEFAULT_FULL

eps: f32

Small positive constant for numerical stability. Default to GaussianNllLoss::DEFAULT_EPS

reduction: LossReduction

Reduction type. Default to GaussianNllLoss::DEFAULT_REDUCTION

Implementations

impl GaussianNllLoss

pub fn new() -> Self

Creates a new instance of GaussianNllLoss.

impl GaussianNllLoss

pub const DEFAULT_FULL: bool = false

Default value for the full parameter.

pub const DEFAULT_EPS: f32 = 9.99999997E-7f32

Default value for the eps parameter.

pub const DEFAULT_REDUCTION: LossReduction = LossReduction::None

Default value for the reduction parameter.

pub fn apply( &self, inputs: impl AsRef<Array>, targets: impl AsRef<Array>, vars: impl AsRef<Array>, ) -> Result<Array, Exception>
