有效性

It is not only a quantity factor but non quantity factor at the same time to be considered, according to the validity of Taylor expansion formula which is nearby the expansion spot, then the author utilizes judging function of adaptive algorithm and dynamic cluster of the parameter to set up the cluster prediction model of the price of financial assets.

考虑了数量化的因素同时也考虑了非数量化的因素，依据泰勒展开公式在展开点附近的有效性，利用参数自适应算法和动态聚类的判断作用建立了金融资产价格的聚类预测模型。

Several cluster validity measures have been proposed for confirming the optimal k value. However, the existing methods may not work well for the following two kinds of data sets: the data set containing cluster groups with different densities and the data set in which the cluster groups are extremely close to each other.

目前，已经提出了许多确定最佳k值的聚类有效性方法，但这些方法都不能很好地处理两种数据集：类密度不同的数据集和类间距比较小的数据集。

It can receive the result through the tree-likes figure and scatter plot.In order to verify models, the results is the same when input same variable with Quick Cluster . The characteristic is very obvious between different groups. It is different of purchase mode and consumption and behavior of different groups. It has proved that the original model is practical and has relatively strong convincingness.

为验证模型，先用快速聚类法输入相同变量得到的结果是一致的，通过对考察对象进行特征分析以及部分变量的拟和分析发现，不同群体间的差异程度是比较明显的，其购买行为、购买模式、消费金额和消费习惯是不相同的，说明原模型具有较强的说服力，从而验证了模型的合理性、有效性和实用性。

The theory analysis shows that this method has a good performance, especially in a heavy clutter environment.

通过理论分析，证明了本方法的有效性，尤其在强干扰的环境中更为明显。
