摘要:

在大多数实际应用中,通常使用来自不同视图的多个特征来表示一个对象。其中,基于多视点子空间的聚类算法得到了研究者的广泛关注,它旨在为多视点数据提供聚类解决方案。然而,大多数现有的方法未能充分利用多视图场景下的局部几何结构和样本之间的相似性关系。为了解决这些问题,本文提出了一种新的带有局部关系约束的多视图学习方法--局部关系约束多视图聚类框架(LRC-MCF)。LRC-MCF通过获取多个视图之间的局部关系信息和共同的相似关系,挖掘不同视图之间的多样性、几何性、一致性和互补性信息。此外,LRC-MCF在寻找共视局部结构时充分考虑了不同视角的权重,并直接产生最终的聚类。为了有效地减少冗余的学习表示,共同的相似性矩阵的低秩约束被认为是额外的。为了解决LRC-MCF的最小化问题,提出了一种交替方向最小化(ADM)方法来迭代计算所有变量的LRC-MCF。在7个基准多视图数据集上的大量实验结果验证了LRC-MCF方法的有效性。

英文摘要:

In most practical applications, it's common to utilize multiple features from different views to represent one object. Among these works, multi-view subspace-based clustering has gained extensive attention from many researchers, which aims to provide clustering solutions to multi-view data. However, most existing methods fail to take full use of the locality geometric structure and similarity relationship among samples under the multi-view scenario. To solve these issues, we propose a novel multi-view learning method with locality relationship constraint to explore the problem of multi-view clustering, called Locality Relationship Constrained Multi-view Clustering Framework (LRC-MCF). LRC-MCF aims to explore the diversity, geometric, consensus and complementary information among different views, by capturing the locality relationship information and the common similarity relationships among multiple views. Moreover, LRC-MCF takes sufficient consideration to weights of different views in finding the common-view locality structure and straightforwardly produce the final clusters. To effectually reduce the redundancy of the learned representations, the low-rank constraint on the common similarity matrix is considered additionally. To solve the minimization problem of LRC-MCF, an Alternating Direction Minimization (ADM) method is provided to iteratively calculate all variables LRC-MCF. Extensive experimental results on seven benchmark multi-view datasets validate the effectiveness of the LRC-MCF method.
