| Abstract(in English) | We propose to learn a hierarchical structure of clusters from continuous data via two-step procedure: We first binarize data points based on nearest neighbor search, followed by applying formal concept analysis (FCA) to the binarized data. FCA constructs a hierarchy of clusters, called a concept lattice, which reveals the hierarchical relationship between data points based on the algebraic closedness property. We empirically show that our method can effectively extract hierarchical structure of clusters, which allows visualization and interpretation of multivariate data. |
