回到我们目标检测中的mAP,这个概念是PASCAL VOC比赛中所明确的metric。它的意思是输出的结果是一个ranked list,里边每一个元素包含了类别、框的信息,以及confidence,这个confidence就用来排序。有了排序,就可以计算AP了,然后再针对所有分类,取一个mean,就得到了mAP。这里为何要排序呢?是因为每一个框有一个con...
假设你的模型一共预测了100个正例,而其中80个是对的正例,那么你的precision就是80%。我们可以把precision也理解为,当你的模型作出一个新的预测时,它的confidence score 是多少,或者它做的这个预测是对的的可能性是多少。 一般来说呢,鱼与熊掌不可兼得。如果你的模型很贪婪,想要覆盖更多的sample,那么它就更有可...

模型就越好。这个曲线下面积就称为 AUC（Area Under the Curve）。
Characteristic）曲线下面的面积越大，模型就越好。这个曲线下面积就称为 AUC（Area Under the Curve）。
It can not be stated with confidence whether the inhibition of GS1 expression is directly related to the KO of GS5 in CHO-S or occur during the selection of subclone. Figure 4 The mRNA expression level of GS genes in each GS-KO clone on day 7 of a batch culture in GS selection ...
S2f, g). Multivariate Cox regression analysis determined that high YTHDF1 expression was an independent prognostic factor for DFS (hazard ratio [HR] = 1.822, 95% confidence interval [CI]: 1.030–2.859; P = 0.038) and OS (HR = 1.824, 95% CI: 1.041–3.194; P = 0.036...

The two dose measures yielded similar maximum likelihood estimates for the cancer risk at concentrations from 10 to 100 ppm, but the upper 95% confidence limit on the risk was reduced by two orders of magnitude when DPX rather than the airborne concentration was used as the measure of exposure...
