摘要：
We present a new method for cluster analysis that finds a composite "supercluster" consisting of two non-overlapping parts: a tight core and a less connected shell. We expand this approach to data that changes over time by assuming that the core is unchangeable, while the shell depends on the time period. We define a data recovery approximation model of a dynamic supercluster, and present a suboptimal algorithm for finding superclusters.
