WebIn two-step clustering [10], BIRCH is extended to mixed data, by adding histograms over the categorical variables. Because BIRCH is sequentially inserting data points into the CF-tree, the tree construction can be suspended at any time. The leaves can then be pro-cessed with a clustering algorithm; when new data arrives the tree construction WebJul 12, 2024 · Step 1: The CF vector and the CF tree are obtained using the enhanced BIRCH algorithm, so as to obtain the density information of the data set. The second stage used the density estimation value of the data set obtained in the first stage as the parameter of the DBSCAN algorithm clusters the density and obtains the clustering results.
