Query: Reliable Agglomerative Clustering   We analyze the general behavior of agglomerative clustering methods, and
argue that their strategy yields establishment of a new reliable linkage at
each step. However, in order to provide adaptive, density-consistent and
flexible solutions, we propose to extract all the reliable linkages at each
step, instead of the smallest one. This leads to a new agglomerative clustering
strategy, called reliable agglomerative clustering, which similar to the
standard agglomerative variant can be applied with all common criteria.
Moreover, we prove that this strategy with the single linkage criterion yields
a minimum spanning tree algorithm. We perform experiments on several real-world
datasets to demonstrate the superior performance of this strategy, compared to
the standard alternative.
