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....

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...

Detecting the community structure in complex networks based on quantum mechanics

Niu, Yan Qing; Hu, Bao Qing; Zhang, Wen; Wang, Min - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 24, pp. 6215-6224

In this paper, we develop a novel method to detect the community structure in complex networks. This approach is based on the combination of kernel-based clustering using quantum mechanics, the spectral clustering technique and the concept of the Bayesian information criterion. We test the...

Short-term wind speed forecasting based on spectral clustering and optimised echo state networks

Liu, Da; Wang, Jilong; Wang, Hui - In: Renewable Energy 78 (2015) C, pp. 599-608

Predicting the wind speed at multiple time points over a time span between two and 4 h typically requires a multi-input/multi-output model. This study investigates a wind speed forecasting method based on spectral clustering (SC) and echo state networks (ESNs). A wavelet transformation was used...

A non-parametric method to estimate the number of clusters

Fujita, André; Takahashi, Daniel Y.; Patriota, Alexandre G. - In: Computational Statistics & Data Analysis 73 (2014) C, pp. 27-39

An important and yet unsolved problem in unsupervised data clustering is how to determine the number of clusters. The proposed slope statistic is a non-parametric and data driven approach for estimating the number of clusters in a dataset. This technique uses the output of any clustering...
