摘要:

基于图的子空间聚类方法表现出良好的性能。然而,它们仍然存在一些缺点:遇到昂贵的时间开销,无法探索显式集群,并且无法推广到看不见的数据点。在这项工作中,我们提出了一个可扩展的图学习框架,寻求同时解决上述三个挑战。具体来说,它是基于锚点和二分图的思想。而不是建立一个$n\times n$图,其中$n$是样本的数量,我们构建一个二分图来描述样本和锚点之间的关系。同时,一个连接性约束,以确保连接组件直接指示集群。我们进一步建立我们的方法和K-均值聚类之间的联系。此外,还提出了一种处理多视图数据的模型,该模型相对于$n$是线性缩放的。大量的实验证明了我们的方法的效率和有效性,相对于许多国家的最先进的聚类方法。

英文摘要:

Graph-based subspace clustering methods have exhibited promising performance. However, they still suffer some of these drawbacks: encounter the expensive time overhead, fail in exploring the explicit clusters, and cannot generalize to unseen data points. In this work, we propose a scalable graph learning framework, seeking to address the above three challenges simultaneously. Specifically, it is based on the ideas of anchor points and bipartite graph. Rather than building a $n\times n$ graph, where $n$ is the number of samples, we construct a bipartite graph to depict the relationship between samples and anchor points. Meanwhile, a connectivity constraint is employed to ensure that the connected components indicate clusters directly. We further establish the connection between our method and the K-means clustering. Moreover, a model to process multi-view data is also proposed, which is linear scaled with respect to $n$. Extensive experiments demonstrate the efficiency and effectiveness of our approach with respect to many state-of-the-art clustering methods.
