NDCG
An information retrieval evaluation metric for assessing ranking quality. It jointly considers the ranking positions and relevance degrees of multiple relevant documents in a result list, and is one of the mainstream metrics used to evaluate the ranking quality of retrieval systems.
Timeline (last 90 days)
The project introduces three standard retrieval evaluation metrics: Hit Rate, MRR (Mean Reciprocal Rank), and NDCG (Normalized Discounted Cumulative Gain).
Retrieval metrics commonly used in RAG evaluation include Hit Rate, Mean Reciprocal Rank (MRR), and Normalized Discounted Cumulative Gain (NDCG).
Offline ranking quality is measured by NDCG, MAP, and MRR, classification prediction accuracy is measured by AUC and LogLoss, and online performance must be validated through A/B testing.
