Web1 de jan. de 2024 · For data fusion we apply a bottom-up hierarchical clustering approach to the binary matrices G. Initially, no patient cluster exists. In each iteration, patients or clusters of patients ( c 1 ∈ C and c 2 ∈ C) fuse to a newly built cluster with minimal distance d m i n, until just one single cluster remains. WebHierarchical agglomerative clustering. Hierarchical clustering algorithms are either top-down or bottom-up. Bottom-up algorithms treat each document as a singleton cluster at the outset and then successively merge (or agglomerate ) pairs of clusters until all clusters have been merged into a single cluster that contains all documents.
