Abstract: Multi-scale clustering plays an important role in multi-scale decision making,which cannot be replaced,while almost of the traditional multi-scale clustering algorithms have encountered the same deadly problem that clustering algorithms are applied on every scale which every user is interested in.To overcome the problem occurred,this paper gave a method of vectorization for the multi-scale characteristic in data and proposed a new multi-scale conversion mechanism of knowledge named WVB-MSCA(Weight Vector Based Multi-Scale Clustering Algorithm) with the help of scale conversion mechanism in earth science.WVB-MSCA applies clustering algorithm on the basic scale selected in advance,and inverses the knowledge gained from basic scale to other scales which users are interested in.Experimental results show that WVB-MSCA is feasible and effective.
