Ranking

A collection of different metrics for ranking models.

AveragePrecisionAtK(total, count)	Computes AP@k (average precision at k) metrics.
DCGAtK(total, count)	Computes Discounted Cumulative Gain at k metric.
MRR(total, count)	Computes Mean Reciprocal Rank (MRR), supporting MRR@k for multiple k values.
NDCGAtK(total, count)	Computes Normalized Discounted Cumulative Gain at k (NDCG@k) metrics.
PrecisionAtK(total, count)	Computes P@k (precision at k) metrics.
RecallAtK(total, count)	Computes R@k (recall at k) metrics.
