Struct RecallEvaluator 

pub struct RecallEvaluator { /* private fields */ }

Recall evaluator for comparing ANN and exact search

Implementations

impl RecallEvaluator

pub fn new(config: EvaluationConfig) -> Self

Create a new recall evaluator

pub fn evaluate_single_query<F, G>( &self, query: &[f32], exact_search: F, ann_search: G, ) -> Result<Vec<QueryMetrics>>

where F: Fn(&[f32], usize) -> Result<Vec<SearchResult>>, G: Fn(&[f32], usize) -> Result<Vec<SearchResult>>,

Evaluate a single query against ground truth

Arguments

• query - Query vector
• exact_search - Function that performs exact search (ground truth)
• ann_search - Function that performs approximate search

Returns

Metrics for each k value in the configuration

pub fn evaluate_batch<F, G>( &self, queries: &[Vec<f32>], exact_search: F, ann_search: G, ) -> Result<Vec<AggregatedMetrics>>

where F: Fn(&[f32], usize) -> Result<Vec<SearchResult>>, G: Fn(&[f32], usize) -> Result<Vec<SearchResult>>,

Evaluate multiple queries and aggregate results

Arguments

• queries - List of query vectors
• exact_search - Function that performs exact search (ground truth)
• ann_search - Function that performs approximate search

Returns

Aggregated metrics for each k value
