precision recall曲线matlab一般使用的都是下面的版本: function[recall, precision, rate]=recall_precision(Wtrue, Dhat)%% Input:% Wtrue = true neighbors [Ntest * Ndataset], can be a full matrix NxN% Dhat = estimated distances%% Output:%% exp. # of good pairs inside hamming ball of radius...

Recall is the fraction of true positives which are detected. Figure 7 shows the precision-recall curves for three cases; the results are almost identical. 精确度是真实的正面侦查的分数。 回忆是被查出真实的正面的分数。 图7显示精确度召回曲线为三个案件; 结果是几乎相同的。 [translate] ...
