| Post subject: | ALGLIB: need to help to use Hirarchical Clustering |
I want to use Agglomerative hierarchical clustering that implemented in ALGLIB. In the main code of Example, the input of this function is a short string.But My dataset is large and is saved to a file, How can I use this data file as input of Agglomerative hierarchical clustering? Example of Agglomerative hierarchical clustering that you see in website: "real_2d_array xy = "[[1,1],[1,2],[4,1],[2,3],[4,1.5]]"; clusterizercreate(s); clusterizersetpoints(s, xy, 2); clusterizerrunahc(s, rep);" |
