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 numbers, if the next digit is from 0 throug...

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...

The ROUND() function is, obviously, most commonly used when you need to round a number to the nearest integer. For example, if you want to calculate the average of a set of numbers, you might need to round the final value up or down so that it’s an integer. ...
