Talk:SUBCLU

This sentence is very confusing: "However, a cluster $$C \subseteq DB$$ in subspace $$S$$ is not necessarily a cluster in $$T \subseteq S$$, since clusters are required to be maximal, and more objects might be contained in the cluster in $$T$$ that contains $$C$$. However, a density-connected set in a subspace $$S$$ is also a density-connected set in $$T \subseteq S$$." My questions are: What is DB? Why when S contains T, and C in S, would the cluster in T have more objects than C? It seems it should be the other way around. Thank you! Sunbeam44 (talk) 15:30, 10 June 2012 (UTC)
