Zhe Liu, Yun Li, Lina Yao, Xianzhi Wang, Feiping Nie

摘要:

传统的多视图聚类方法通过最小化一致视图和子视图之间的成对差异来寻求视图一致性。然而,成对比较不能精确地描绘视图间的关系,如果一些子视图可以进一步聚集。为了解决上述问题,我们提出了凝聚分析近似的最佳共识视图,从而描述了一个视图结构内的子视图关系。我们提出了基于约束拉普拉斯秩的聚集神经网络(ANN)来直接聚类多视图数据,同时避免了专用的后处理步骤(例如,使用K-means)。我们进一步扩展ANN与可学习的数据空间来处理复杂场景的数据。我们的评估对几个国家的最先进的多视图聚类方法在四个流行的数据集显示了有前途的观点一致性分析能力的人工神经网络。我们进一步证明了人工神经网络的能力,在分析复杂的视图结构和可扩展性,在我们的案例研究,并解释其鲁棒性和有效性的数据驱动的修改。

英文摘要:

Conventional multi-view clustering methods seek for a view consensus through minimizing the pairwise discrepancy between the consensus and subviews. However, the pairwise comparison cannot portray the inter-view relationship precisely if some of the subviews can be further agglomerated. To address the above challenge, we propose the agglomerative analysis to approximate the optimal consensus view, thereby describing the subview relationship within a view structure. We present Agglomerative Neural Network (ANN) based on Constrained Laplacian Rank to cluster multi-view data directly while avoiding a dedicated postprocessing step (e.g., using K-means). We further extend ANN with learnable data space to handle data of complex scenarios. Our evaluations against several state-of-the-art multi-view clustering approaches on four popular datasets show the promising view-consensus analysis ability of ANN. We further demonstrate ANN's capability in analyzing complex view structures and extensibility in our case study and explain its robustness and effectiveness of data-driven modifications.
