A Method of Clustering Ensemble Based on Grey Relation Analysis
Wireless Personal Communications, 2018Clustering ensemble algorithm is an effective way to improve the accuracy, stability and robustness of clustering results. It can get better results by fusing multiple homogenous or heterogeneous base clustering models. In this paper a clustering ensemble algorithm based on grey relation analysis is proposed.

Application of Grey Relational Analysis for Multivariate Time Series
2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008Grey relational analysis (GRA) has been widely applied in analysing multivariate time series data (MTS). It is an alternate solution to the traditional statistical limitations. GRA is employed to search for grey relational grade (GRG) which can be used to describe the relationships between the data attributes and to determine the important factors that
