Struct PatternAffinityClassifier 

pub struct PatternAffinityClassifier { /* private fields */ }

Pattern Affinity Classifier for routing-drift protection.

Central component that computes affinity scores and provides gating decisions for pattern extraction pipeline.

Implementations

impl PatternAffinityClassifier

pub fn new() -> Self

Create classifier with default thresholds.

pub fn with_config(affinity_threshold: f32, min_success_rate: f32) -> Self

Create classifier with custom thresholds.

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

Compute relative affinity for an episode against pattern clusters.

This is the core Drel computation from DyMoE:

• Compares episode embedding to centroids of old and new patterns
• Returns relative difference to detect ambiguous episodes

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

Create assignment guard for an episode.

Combines episode’s success rate with computed affinity clarity.

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

Check if episode should be gated from pattern mutation.

Returns true if the episode is ambiguous and should NOT mutate existing high-performing patterns.

pub fn affinity_threshold(&self) -> f32

Get the configured affinity threshold.

pub fn min_success_rate(&self) -> f32

Get the configured minimum success rate.

Trait Implementations

impl Clone for PatternAffinityClassifier

fn clone(&self) -> PatternAffinityClassifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PatternAffinityClassifier

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

Formats the value using the given formatter.

impl Default for PatternAffinityClassifier

fn default() -> Self

Returns the “default value” for a type.
