Random walk distances in data clustering and applications

Liu, Sijia; Matzavinos, Anastasios; Sethuraman, Sunder - In: Advances in Data Analysis and Classification 7 (2013) 1, pp. 83-108

In this paper, we develop a family of data clustering algorithms that combine the strengths of existing spectral approaches to clustering with various desirable properties of fuzzy methods. In particular, we show that the developed method “Fuzzy-RW,” outperforms other frequently used...

Selection of the number of clusters via the bootstrap method

Fang, Yixin; Wang, Junhui - In: Computational Statistics & Data Analysis 56 (2012) 3, pp. 468-477

Here the problem of selecting the number of clusters in cluster analysis is considered. Recently, the concept of clustering stability, which measures the robustness of any given clustering algorithm, has been utilized in Wang (2010) for selecting the number of clusters through cross validation....
