Struct RelativeAffinity 

pub struct RelativeAffinity {
    pub score_old: f32,
    pub score_new: f32,
    pub drel: f32,
}

Relative affinity between new and old pattern clusters.

Drel measures how clearly an episode belongs to new vs old patterns.

• Drel ≈ 0: Episode is ambiguous (similar scores to both clusters)
• Drel ≈ 1: Episode clearly belongs to one cluster

Formula: Drel = |score_new - score_old| / max(score_new, score_old)

Fields

score_old: f32

Affinity score to old/existing patterns

score_new: f32

Affinity score to new/potential patterns

drel: f32

Relative difference (computed)

Implementations

impl RelativeAffinity

pub fn compute( episode: &Episode, old_patterns: &[Pattern], new_patterns: &[Pattern], episode_embedding: Option<&[f32]>, ) -> Self

Compute relative affinity between episode and pattern clusters.

Uses max cosine similarity to find the best match in each cluster.

pub fn is_ambiguous(&self, threshold: f32) -> bool

Check if this affinity is ambiguous (Drel < threshold).

pub fn clarity(&self) -> f32

Get the clarity score (1 - Drel normalized). Higher clarity means the episode clearly belongs to one cluster.

Trait Implementations

impl Clone for RelativeAffinity

fn clone(&self) -> RelativeAffinity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelativeAffinity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RelativeAffinity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RelativeAffinity

fn eq(&self, other: &RelativeAffinity) -> 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 RelativeAffinity

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RelativeAffinity
