The two-step algorithm uses the(agglomerative) hierarchical clustering method, because it works well with the auto-cluster method. The algorithm is based on a distance measure that gives the best results if all variables are independent, the continuous variables have a normal distribution, and the categorical variables have a multinomial distribution.  2, record 1, English, - two%2Dstep%20algorithm

two-step algorithm: A "two-step algorithm" should not be confused with a "two-stage algorithm." "Two-step" refers to a process involving two sequential actions, while "two-stage" implies a process with distinct levels or phases of operation.  3, record 1, English, - two%2Dstep%20algorithm

[...] l'algorithme BIRCH [...] a été développé pour permettre le traitement de grands volumes de données dans un espace mémoire restreint. Pour ce faire, BIRCH réduit la taille du jeu de données initial en le résumant sous la forme d'une structure hiérarchique [...] dans laquelle les points sont agrégés successivement en fonction de leur similarité et de l'espace mémoire disponible.  2, record 2, French, - algorithme%20BIRCH

Agglomerative hierachy clustering algorithm. This is the most common type of hierarchical clustering algorithm. It's used to group objects in clusters based on how similar they are to each other. This is a form of bottom-up clustering, where each data point is assigned to its own cluster. Then those clusters get joined together. At each iteration, similar clusters are merged until all of the data points are part of one big root cluster.  1, record 3, English, - agglomerative%20hierarchy%20clustering%20algorithm

Monothetic clustering is a divisive clustering method that uses a hierarchical, recursive partitioning of multivariate responses based on binary decision rules that are built from individual response variables... Based on the ideas of classification and regression trees, a monothetic clustering algorithm was implemented... to allow further explorations and modifications.  2, record 5, English, - monothetic%20clustering%20algorithm
