Enum PAVariant 

pub enum PAVariant {
    PA,
    PAI,
    PAII,
}

Selects the PA update variant.

Variants

PA

Unconstrained PA: τ = loss / ||x||².

PAI

PA-I: τ = min(C, loss / ||x||²).

PAII

PA-II: τ = loss / (||x||² + 1 / (2C)).

Trait Implementations

impl Clone for PAVariant

fn clone(&self) -> PAVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PAVariant

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

Formats the value using the given formatter.

impl PartialEq for PAVariant

fn eq(&self, other: &PAVariant) -> 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.
