The description has been updated to reflect a more [standard](https://en.wikipedia.org/wiki/Evaluation_measures_(information_retrieval)#Mean_average_precision) presentation of the metric.\n\nIt is important to note that the `MAP@k` metric calculation **is not changing** and this in no way affects scores; rather, the equation on the evaluation page has just been updated to a standard (and much clearer) format.\n",
