Type I and type II errors occur during statistical hypothesis testing. While the type I error (a false positive) rejects a null hypothesis when it is, in fact, correct, the type II error (a false negative) fails to reject a false null hypothesis. For example, a type I error would conv...
正样本(positive example )和负样本(negative example) 单独针对某个分类,与GT的IOU大于上门限的bbox是正样例,同理,与GT的IOU低于下门限bbox是负样例,在代码中可以将正样本理解为前景,负样本理解为背景,但不是主观上的前景和背景 如下图,对“person”分类时,其他bbox均为负样本 easy negative example...Type...

1. 定义 A Type I error is the risk of rejection of a true null hypothesis. Another way of phrasing this is that it is a false positive result; that is, the null is rejected (the positive), yet the null is true (hence, a false positive). The expected portion of false positives is...
Which error would you say is more serious? A false positive (type I error) — when you reject a true null hypothesis — or a false negative (type II error) — when you accept a false null hypothesis? I read in many places that the answer to this question is: a false positive. I ...
It is emphasized that two types of errors are made in the testing of a hypothesis, false positive (type I) and false negative (type II). Genome-wide scans involving many markers give rise to the problem of multiple testing, which results in an increased number of false positives, thus nec...

Type II error,II类错误,也叫做β错误 FP: false positive,假正例,I类错误 FN: false negative,假反例,II类错误 TP: true positive,真正例 TN: true negative,真反例 I类错误是指空假设为真却被我们拒绝的情况,犯这种错误的概率用α表示,所以也称为α错误或弃真错误;II类错误是指空假设为假但我们没有拒...

The following sample code long offset(long v) { if (!v) return 0; if (v > 0) return 1; if (v < 0) return -1; } produces warning: non-void function does not return a value in all control paths [-Wreturn-type] So does long offset(long v) {...
