All quality metrics for a single query evaluation.
Fields§
§recall_at_k: f64|relevant ∩ results@K| / min(|relevant|, K)
precision_at_k: f64|relevant ∩ results@K| / K
ndcg_at_k: f64Normalised Discounted Cumulative Gain at K (binary relevance).
average_precision: f64Average Precision — area under the precision-recall curve up to K.
reciprocal_rank: f64Reciprocal Rank — 1 / rank of the first relevant result (0 if none).
