Intrinsic Weight Learning Approach for Multi-view Clustering
This work addresses the challenge of handling noisy or varying capacities in multi-view data for clustering, though it appears incremental as it builds on existing weight-based methods.
The paper tackles the problem of measuring view importance in multi-view clustering by proposing a new intrinsic weight learning paradigm based on a re-weighted approach, and it demonstrates effectiveness in numerical experiments.
Exploiting different representations, or views, of the same object for better clustering has become very popular these days, which is conventionally called multi-view clustering. Generally, it is essential to measure the importance of each individual view, due to some noises, or inherent capacities in description. Many previous works model the view importance as weight, which is simple but effective empirically. In this paper, instead of following the traditional thoughts, we propose a new weight learning paradigm in context of multi-view clustering in virtue of the idea of re-weighted approach, and we theoretically analyze its working mechanism. Meanwhile, as a carefully achieved example, all of the views are connected by exploring a unified Laplacian rank constrained graph, which will be a representative method to compare with other weight learning approaches in experiments. Furthermore, the proposed weight learning strategy is much suitable for multi-view data, and it can be naturally integrated with many existing clustering learners. According to the numerical experiments, the proposed intrinsic weight learning approach is proved effective and practical to use in multi-view clustering.
