非负数

Non-negative matrix factorization is a newly popular method for non-negative dimensionality reduction, feature extraction, data mining, etc.

摘要非负矩阵分解(Non-negative matrix factorization， NMF)是一个近年来非常流行的非负数据处理方法，它常用于维数约减、特征提取和数据挖掘等。

The loop still displays NUMLINES lines of text, but for nonzero values of iVscrollPos this value is negative.

这个循环仍然显示 NUMLINES 行文本，但是对于非零值的 iVscrollPos 这个值是负数。

Note that unsigned numbers on a signed magnitude machine are equivalent to signed non-negative numbers as a consequence of the forced correspondence between addresses and unsigned numbers and of the required behavior of + and -.

注意在一个有号量机器上，无号数是相等於有号的非负数，作为一个强迫对应於位址和无号数而且需要+和-行为的影响。
