Round to nearest Fields: AwayFromZero ToEven A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. For positive nu...
Round to nearest, ties away from zero – rounds to the nearest value; if the number falls midw...
K-nearest neighbor(KNN)是机器学习中最受欢迎的算法之一,被广泛应用于监督学习和无监督学习。在监督学习中,KNN用于计算与k个邻居的距离,并可以定义离群值。而在无监督学习中,KNN也可以用于计算邻居的距离,然后定义离群值。在PyOD中,KNN算法主要用于无监督学习。本文将讨论KNN在监督学习和无监督学习中的应用以及如何...

对于每个数据点,找到它的 k-nearest-neighbor,计算 LOF 得分; 如果LOF值越大,说明越异常,反之如果越小,说明越趋于正常。 四、LOF优缺点 优点 LOF 的一个优点是它同时考虑了数据集的局部和全局属性。异常值不是按绝对值确定的,而是相对于它们的邻域点密度确定的。当数据集中存在不同密度的不同集群时,LOF表现良...
