@coderxiang k should be a configurable parameter in ranking metrics, e.g., prec@1 and prec@5. The API could be

def precision(k: Int): Double
def ndcg(k: Int): Double

@mengxr @coderxiang Hm come to think of it, doesn't this duplicate a lot of the purpose of https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/mllib/evaluation/MulticlassMetrics.scala ? It also computes precision and recall, and supports multi-class classification instead of the binary case only. It feels like these two should be rationalized and not have two unrelated implementations.

@srowen Ranking metrics are different from multiclass metrics. In general, multiclass metrics do not consider the ordering of the predictions, but just hits and misses, and they don't truncate the result. Ranking metrics consider the ordering of predictions, applying discounts and truncating the result. I think they are two sets of evaluation metrics.

@mengxr Yes I understand these metrics. Precision / recall are binary classifier metrics at heart (but not nDCG for example). Precision@k needs ranking. That's why precision/recall turn up in MulticlassMetrics as a special case -- you can compute precision of class-i vs not-class-i.

I understand it is two views on the same metric, and these are collections of different metrics. Hm, maybe this makes more sense if the metrics here are clearly precision@k, recall@k, with an argument k. The other class has F-measure, true positive rate, etc. I suppose those could be implemented here too for consistency, but don't know how useful they are.

Meh, anything to rationalize the purposeful difference between these two would help. Maybe it's just me.

@srowen Making k explicit is what I suggested to @coderxiang . This should clearly tell the difference from other metrics. F-measure may not be useful here, nor recall. Let's focus on ndcg@k, prec@k, and MAP in this PR. @coderxiang Does it sound good to you?

Can one of the admins verify this patch?

@mengxr @srowen Sorry for late response. In the update, I added two new members that support computing prec@k and ndcg@k, as suggested by @mengxr . Specifically, if k is too large, prec@k will be calculated as normal while ndcg@k will use the last computed value, as used in this paper. We can further discuss whether this is the best option.
