在多视图聚类问题中,视图间的互补性信息与差异性信息会给聚类效果带来影响;同时样本点包含的重要性信息不同,也会对聚类效果产生不同的干扰。现有方法有些没有充分利用视图间的互补性信息,或者没有利用各视图间的差异性信息和样本点中的重要性信息,导致聚类效果不佳。针对上述问题,本文提出基于自相关矩阵的自适应多视图融合聚类算法(Adaptive Multi-view-fusion Clustering based on Self-correlative Matrix
AMCSM)。首先,使用特征直连技术,以更好地利用视图间的互补性信息;其次,使用自动权重机制为各视图自适应地分配适当的权重,以充分利用视图间的差异性信息;最后,对各视图施加对角的加权矩阵,并联合自相关矩阵以充分利用样本点中的重要性信息。设计统一的多步迭代框架将上述优化方案整合一起,使视图互补性信息、视图差异性信息与样本点重要性信息在迭代过程中相互促进、相互学习。实验结果表明,在灵敏度、精准度、特异度、调整兰德系数和马修斯相关系数等评价指标上,本文所提算法均取得优良结果且更具鲁棒性。
In multi-view clustering problems
the complementary information and difference information between views have impact on the clustering effect
while the importance conveyed by the sample points also affects the clustering effect. Some existing methods do not fully utilize the complementary information between views
some do not consider the difference information between views
and some do not utilize the importance of sample points
resulting in poor clustering performance. To address the above issues
an adaptive multi-view-fusion clustering algorithm based on self-correlative matrix (AMCSM) is proposed. Firstly
feature concatenating is used to better utilize complementary information between views; Secondly
the auto-weighted mechanism is introduced to adaptively assign appropriate weights to each view
to fully utilize the difference information between views; Finally
diagonal weighted matrices and self-correlative matrices are simultaneously utilized to mine important information conveyed by the sample points. A unified multi-step iterative framework is designed to integrate the above optimization solutions
so that complementary information
difference information
and important information of sample points can promote and learn from each other during the iteration process. The experimental results show that the proposed algorithm achieves excellent results in evaluation metrics such as sensitivity
precision
specificity
adjusted Rand Index
and Matthews correlation coefficient
which is more robust.
