The k-modes clustering algorithm is undoubtedly one of the most widely used partitional algorithms for categorical data. Unfortunately, due to its gradient descent nature, this algorithm is highly sensitive to the initialization of clustering. Categorical initialization methods have been proposed to address this problem. In this paper, we present an overview of initialization methods of clustering...
In order to solve the communication conflict of the mine personnel positioning system, clustering protocol is employed, in which the node receiving the strongest signal is selected as the new head of the cluster and the members are selected based on the method of RSSI similarity and neighbor node K. Simulation on clustering protocol was performed using the software MATLAB. It indicated that the speed...
The distributed routing protocol is widely used in wireless sensor networks. But it is mainly designed for homogeneous networks and also has the disadvantages of irrationality of choosing cluster head and unbalanced energy consumption of nodes. Through theoretical studies, a new protocol of the cluster multi-hop transmission (CMHT) for heterogeneous sensor networks is proposed. The algorithm selects...
The premise of the enterprise that implements the product family architecture is the analysis to the sailed products history data, carrying on accuracy demarcation of the customer sets and products sets. But, the traditional cluster methods consist in simultaneous one partitioning of the set of products or the set of customers. In this paper we review the most widely used and successful biclustering...
