In addition , the domain for every class can be decided correctly by the model ' s self - regulating function and the samples that were initially classified to unapproprite classes are adjusted to appropriate classes , which eliminates the adverse effects caused by man - made subjective factors to make analytic results more objective 此外，通过模型的自动调节作用，可正确划分各类别域值，并对初始聚类不符合的样本调整归入正确类别，消除人为主观因素造成的不利影响，使分析结果更符合实际。
Military science , seeing in history an immense number of examples in which the mass of an army does not correspond with its force , and in which small numbers conquer large ones , vaguely recognises the existence of this unknown factor , and tries to find it sometimes in some geometrical disposition of the troops , sometimes in the superiority of weapons , and most often in the genius of the leaders 历史上有数不清的军队的数量与力量不符合的例子小部队打败大部队，于是军事学上便含糊其辞地承认，有一种未知的因子存在，军事学家力图在几何阵形在军队的装备最常见的在统帅的天才上寻找这一未知的因子。
