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)
