Enum NegativeSampler 

pub enum NegativeSampler {
    Uniform,
    TypeConstrained,
    SelfAdversarial {
        temperature: f64,
    },
}

Strategy used to generate corrupted (negative) triples from a positive one.

Variants

Uniform

Randomly replace head or tail with any entity drawn uniformly at random.

TypeConstrained

Replace only with entities that appear in the same position (head or tail) across the observed triple set — provides type-constrained negatives.

SelfAdversarial

Self-adversarial sampling: weight candidates proportionally to their current model score so hard negatives are sampled more often.

Fields

temperature: f64

Temperature parameter controlling sharpness of the distribution. Higher temperature → more uniform; lower temperature → harder negatives.

Trait Implementations

impl Clone for NegativeSampler

fn clone(&self) -> NegativeSampler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NegativeSampler

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NegativeSampler

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NegativeSampler

fn eq(&self, other: &NegativeSampler) -> 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 Serialize for NegativeSampler

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
