描述----------Description----------
The objects of class "fanny" represent a fuzzy clustering of a dataset.
类的对象"fanny"代表了数据集的模糊聚类。
值----------Value----------
A legitimate fanny object is a list with the following components:
一个合法的fanny对象是一个具有下列组件的列表:
参数:membership
matrix containing the memberships for each pair consisting of an observation and a cluster.
矩阵包含对每个组成的观察和群集的成员。
参数:memb.exp
the membership exponent used in the fitting criterion.
会员指数在装修标准。
参数:coeff
Dunn's partition coefficient F(k) of the clustering, where k is the number of clusters. F(k) is the sum of all squared membership coefficients, divided by the number of observations. Its value is between 1/k and 1. The normalized form of the coefficient is also given. It is defined as (F(k) - 1/k) / (1 - 1/k), and ranges between 0 and 1. A low value of Dunn's coefficient indicates a very fuzzy clustering, whereas a value close to 1 indicates a near-crisp clustering.
唐恩的分配系数F(k)聚类,其中k是簇的数目。 F(k)是所有平方成员系数总和,除以若干意见。它的值是1/k和1之间。也给出了系数的规范化形式。它被定义为(F(k) - 1/k) / (1 - 1/k),0和1之间的范围。一个唐恩系数低价值表示非常模糊聚类,而一个值接近1,表示附近的一个清脆的聚类。
参数:clustering
the clustering vector of the nearest crisp clustering, see partition.object.
在最近的脆聚类的聚类向量,看到partition.object。
参数:k.crisp
integer (<= k) giving the number of crisp clusters; can be less than k, where it's recommended to decrease memb.exp.
整数(<= k)发出清脆集群的数量;可以比k,它建议,以减少memb.exp。
参数:objective
named vector containing the minimal value of the objective function reached by the FANNY algorithm and the relative convergence tolerance tol used.
命名为向量,含有范妮算法和相对收敛公差tol使用所达成的目标函数的极小值。
参数:convergence
named vector with iterations, the number of iterations needed and converged indicating if the algorithm converged (in maxit iterations within convergence tolerance tol).
命名为向量,用iterations所需的迭代次数和converged表示,如果该算法融合(maxit内迭代收敛公差tol)。
参数:diss
an object of class "dissimilarity", see partition.object.
一个"dissimilarity"类的对象,看到partition.object。
参数:call
generating call, see partition.object.
产生呼叫,看到partition.object。
参数:silinfo
list with silhouette information of the nearest crisp clustering, see partition.object.
与就近的清脆的聚类轮廓信息的列表,请参阅partition.object。
参数:data
matrix, possibibly standardized, or NULL, see partition.object.
矩阵,possibibly规范,或NULL,看到partition.object。
发电----------GENERATION----------
These objects are returned from fanny.
从fanny这些对象返回。
方法----------METHODS----------
The "fanny" class has methods for the following generic functions: print, summary.
"fanny"类有以下的通用功能的方法:print,summary。
遗传----------INHERITANCE----------
The class "fanny" inherits from "partition". Therefore, the generic functions plot and clusplot can be used on a fanny object.
从"fanny"类"partition"继承。因此,通用的功能plot和clusplot可以fanny对象的使用。
