Abstract
A computer-implemented method for clustering a plurality of observations included in a dataset. The method includes selecting a subset of variables from a set of variables, where each variable in the subset is associated with each observation in the dataset; for each of a first number of times, randomly selecting an initial value for each variable in the subset to generate a seed value set that includes an initial value for each variable in the subset; generating a number of pre-clusters equal to the first number based on a similarity between each observation in the dataset and each of the first number of seed value sets; and applying a hierarchical clustering algorithm to the first number of pre-clusters to derive a second number of clusters.
