MRR (Mean Reciprocal Rank) Metric

What is MRR (Mean Reciprocal Rank) Metric?

The MRR (Mean Reciprocal Rank) metric evaluates the average reciprocal rank of the first relevant result in a list. This metric is particularly useful for tasks where identifying the first correct answer is crucial, such as search engine query responses or recommendation systems. By focusing on the position of the correct answer, MRR helps measure the effectiveness of ranking algorithms in prioritizing relevant results.
