is proposed to solve the sensitivity of scaling parameter of spectral clustering. The algorithm utilizes the good robustness and generalization ability of ensemble learning. The property of spectral clustering is exploited to generate the components for integrating learning
and the Hungarian algorithm is used to relabel the resulting component clusterings. Then a compositional data vector is obtained by computing the ratio of each label for each sample. The compositional data vectors are mapped into another space via log contrast transform to solve the ill-posed characteristic of compositional data. The final aggregated results are generated by clustering the mapped data. Experiments on UCI data and texture images show that the proposed algorithm is comparable with some common consensus functions in accuracy
its computational cost is about half of that of MCLA
and it avoids the selection of the accurate parameter in spectral clustering.
