摘要:

给定一个数据集和一个现有的聚类作为输入,替代聚类的目的是找到一个替代的分区。最先进的方法之一是核维交替聚类(KDAC)。我们提出了一种新的迭代谱方法(ISM),大大提高了KDAC的可扩展性。我们的算法是直观的,依赖于易于实现的频谱分解,并与理论保证。它的计算时间比现有的KDAC实现提高了5个数量级。

英文摘要:

Given a dataset and an existing clustering as input, alternative clustering aims to find an alternative partition. One of the state-of-the-art approaches is Kernel Dimension Alternative Clustering (KDAC). We propose a novel Iterative Spectral Method (ISM) that greatly improves the scalability of KDAC. Our algorithm is intuitive, relies on easily implementable spectral decompositions, and comes with theoretical guarantees. Its computation time improves upon existing implementations of KDAC by as much as 5 orders of magnitude.
