用神经网络结构同时进行Dempster-Shafer聚类和逐步确定聚类数

Simultaneous Dempster-Shafer clustering and gradual determination of number of clusters using a neural network structure

Johan Schubert

摘要:

在本文中,我们扩展了Dempster-Shafer理论中的早期结果[“Fast Dempster-Shafer Clustering Using a神经网络Structure,”in Proc. Seventh Int. Conf.信息处理and Management of Uncertainty in Knowledge-Based Systems(IPMU'98)],其中使用神经结构将多个证据聚类为固定数量的聚类。这是通过最小化元冲突函数来完成的。现在,我们开发了一种方法,同时聚类和集群的数量在迭代过程中的神经结构的确定。我们让神经元的输出信号代表证据属于相应聚类的程度。从这些,我们得到一个概率分布的集群的数量,这逐渐在迭代过程中转化为集群的数量的确定。这种逐渐确定在每次迭代时被反馈到神经结构中以影响聚类过程。

英文摘要:

In this paper we extend an earlier result within Dempster-Shafer theory ["Fast Dempster-Shafer Clustering Using a Neural Network Structure," in Proc. Seventh Int. Conf. Information Processing and Management of Uncertainty in Knowledge-Based Systems (IPMU'98)] where several pieces of evidence were clustered into a fixed number of clusters using a neural structure. This was done by minimizing a metaconflict function. We now develop a method for simultaneous clustering and determination of number of clusters during iteration in the neural structure. We let the output signals of neurons represent the degree to which a pieces of evidence belong to a corresponding cluster. From these we derive a probability distribution regarding the number of clusters, which gradually during the iteration is transformed into a determination of number of clusters. This gradual determination is fed back into the neural structure at each iteration to influence the clustering process.
