MMR metric

The **MMR metric** (Mean Reciprocal Rank) is a valuable evaluation measure commonly used in information retrieval and ranking systems. It calculates the average of the reciprocal ranks of results for a set of queries, providing insight into how quickly relevant items appear in search results. This metric is particularly useful for assessing the effectiveness of search engines, recommendation systems, and other applications where the order of results impacts user satisfaction. Use the MMR metric tag to categorize content related to ranking evaluation, search quality metrics, and performance analysis of retrieval algorithms.
