Consensus Kernel K-Means Clustering for Incomplete Multiview Data

الملخص EN

Multiview clustering aims to improve clustering performance through optimal integration of information from multiple views.

Though demonstrating promising performance in various applications, existing multiview clustering algorithms cannot effectively handle the view’s incompleteness.

Recently, one pioneering work was proposed that handled this issue by integrating multiview clustering and imputation into a unified learning framework.

While its framework is elegant, we observe that it overlooks the consistency between views, which leads to a reduction in the clustering performance.

In order to address this issue, we propose a new unified learning method for incomplete multiview clustering, which simultaneously imputes the incomplete views and learns a consistent clustering result with explicit modeling of between-view consistency.

More specifically, the similarity between each view’s clustering result and the consistent clustering result is measured.

The consistency between views is then modeled using the sum of these similarities.

Incomplete views are imputed to achieve an optimal clustering result in each view, while maintaining between-view consistency.

Extensive comparisons with state-of-the-art methods on both synthetic and real-world incomplete multiview datasets validate the superiority of the proposed method.
