Retrieval Evaluation Metrics Explained: P@K, MRR, NDCG

This article explains key retrieval evaluation metrics used to assess the performance of retrieval systems, including Precision@K (P@K), Recall@k, Mean Reciprocal Rank (MRR), and Normalized Discounted Cumulative Gain (NDCG@K). It highlights how these metrics capture different aspects of ranking quality and can sometimes yield conflicting results. The tutorial also provides Python code to build an evaluation harness for computing these metrics, simulating comparisons between different retrieval architectures, and generating visualizations for deployment decisions.
