说明：  本实验目的是了解非参数估计—Parzen窗估计，对表格3中的数据进行Parzen窗估计和设计分类器.Parzen窗方法：假设区间Rn是一个d维的超立方体，hn表示超立方体的边长，体积为Vn=hnd。
(Purpose of this study is to understand the non-parametric estimation-Parzen window estimate of the data in Table 3 Parzen window estimate and design classifiers. Parzen window method: Suppose a d-dimensional interval Rn is the hypercube, hn that side of the hypercube , volume Vn = hnd.)
