多变量密度估计 multivariate density estimation
The result indicates the algorithm can wipe off the noise effectively and find out the multi-density cluster. The clustering result is good.
算法在人工数据集上进行了实验,结果表明该算法能有效地去除噪声,发现多密度的簇,具有较好的聚类效果。

多密度是什么意思?
然后,分别讨论了利用问卷调查、多密度空间聚类和数据规格化的方法计算POI对象的各项显著性指标值的过程;
Then, the processes of computing the vector values of POI objects are discussed by the methods of questionnaire survey, multi-density spatial clustering and data normalization respectively.
So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.
比如,可能它的形式电荷为负一,因为在一定程度上它得到了这么多的共用电子密度,那么它现在就有了负的形式电荷。
So you can think about how these 2 things combined are going to be electronegativity, which is a measure of how much an atom wants to pull electron density away from another atom.
因此你可以想象出,这两样性质合起来就是电负性,也就是一个度量,关于一个原子,有多希望把另一个原子的电子密度拉过来的。
Because we know as we go to infinity, even though the density gets smaller and smaller and smaller, we still have electron density very far away from the nucleus.
因为我们知道即使到了无穷远处,尽管电子密度会变得非常非常非常小,但我们仍然有一定的电子密度,无论离原子核多远。
