Struct AnomalyDetectionService 

pub struct AnomalyDetectionService { /* private fields */ }

Service for detecting anomalous embeddings.

Implementations

impl AnomalyDetectionService

pub fn new(threshold: f32, k_neighbors: usize) -> Self

Create a new anomaly detection service.

Arguments

• threshold - Score threshold above which points are considered anomalous
• k_neighbors - Number of neighbors for LOF computation

pub fn default_service() -> Self

Create with default settings.

pub async fn detect_anomalies( &self, embeddings: &[EmbeddingWithId], clusters: &[Cluster], ) -> Result<Vec<Anomaly>>

Detect anomalies among embeddings based on cluster assignments.

Arguments

• embeddings - All embeddings with IDs
• clusters - Discovered clusters

Returns

A vector of detected anomalies.

pub async fn compute_lof( &self, embeddings: &[EmbeddingWithId], ) -> Result<HashMap<EmbeddingId, f32>>

Compute local outlier factor for embeddings.

pub fn classify_anomaly( &self, anomaly: &Anomaly, cluster_member_count: usize, ) -> AnomalyType

Classify the type of anomaly based on context.

Trait Implementations

impl Default for AnomalyDetectionService

fn default() -> Self

Returns the “default value” for a type.
