Abstract(in English) | This paper presents a clustering and embedding method to analyze data which lie on a union of multiple manifolds having different scales. The proposed method executes the following two processes alternately: (i) data are clustered by using bases of the manifolds, and (ii) the bases are updated based on the clustered data. To achieve this, the task is cast as maximization of the variance of data mapped to a subspace of the reproducing kernel Hilbert space that corresponds to the relevant manifold of each cluster. The optimization problem involves real-valued variables to construct the bases and binary variables to assign each datum to its corresponding cluster. Each set of variables is updated in an alternate fashion. For sake of scalability, we extend the domain of the binary variables to the whole Euclidean space under normalization subject to the orthonormality constraint. Despite the nonconvexity of the constraint, the problem in terms of each set of variables admits an analytic solution. The efficacy of the proposed algorithm is demonstrated by simulations using toy data. |
