Enum Reduction 

pub enum Reduction {
    Mean,
    Sum,
    None,
}

Reduction mode for loss functions.

Controls how the per-element losses are aggregated:

• Mean (default): average over all elements
• Sum: sum over all elements
• None: return per-element losses (no reduction)

Variants

Mean

Return the mean of all per-element losses (default).

Sum

Return the sum of all per-element losses.

None

Return per-element losses without reduction.

Trait Implementations

impl Clone for Reduction

fn clone(&self) -> Reduction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Reduction

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Reduction

fn default() -> Reduction

Returns the “default value” for a type.

impl PartialEq for Reduction

fn eq(&self, other: &Reduction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Reduction

impl Eq for Reduction

impl StructuralPartialEq for Reduction
