some data on the Internet) It is usually difficult and time-consuming to locate and obtain We cannot make predictions. Allow us to make predictions and outlook We also need to explore the differences and relationships between statistics (Statistic) and KDD.

columns, where the random number is generated by the standard uniform distribution (U (0,1)).RNG (' Default '); % for ReproducibiltyX = rand (20000,3);Use Ward's linkage to generate hierarchical clustering trees. Set ' savememory ' to ' on ' to construct the cluster but not to calculate the distance matrix.c = Clusterdata (X, ' linkage ', ' ward ', ' savememory ', ' on ', ' Maxclust ', 4);Plot the data into a graphic, where each category corresponds

Example Compare Cluster Assignments to ClustersImport the sample data.Load FisheririsFrom the Anderson Iris Floral Data set, the ward linkage calculates four clusters and ignores the type information.Z = Linkage (MEAs, ' Ward ', ' Euclidean ');c = Cluster (Z, ' Maxclust ', 4);The relationship between cluster results and three species was observed.Crosstab (c,species)Print the first 5 lines of Z.firstfive = Z (1:5,:)Generates a system tree graph

following conditions are available:Linkage is ' centroid ', ' median ' or ' ward 'Distance is ' Euclidean ' (default)When Savememory is ' on ', the linkage run time and the number of dimensions (number of columns in x) are proportional. When Savememory is ' off ', the demand for linkage memory is proportional to N2, where n is the number of observations. The best (and least time-consuming) savememory settings for all choices depend on the dimension of the problem, the number of observations, or
