Improvement of K Mean Clustering Algorithm Based on Density

2018-10-09 · Su Chang, Xu Zhenzong, Gao Xuan

The purpose of this paper is to improve the traditional K-means algorithm. In the traditional K mean clustering algorithm, the initial clustering centers are generated randomly in the data set. It is easy to fall into the local minimum solution when the initial cluster centers are randomly generated. The initial clustering center selected by K-means clustering algorithm which based on density is more representative. The experimental results show that the improved K clustering algorithm can eliminate the dependence on the initial cluster, and the accuracy of clustering is improved.

Clustering via Mode Seeking by Direct Estimation of the Gradient of a Log-Density

2014-04-20 · Hiroaki Sasaki, Aapo Hyvärinen, Masashi Sugiyama

Mean shift clustering finds the modes of the data probability density by identifying the zero points of the density gradient. Since it does not require to fix the number of clusters in advance, the mean shift has been a …

Clustering of Big Data with Mixed Features

Clustering large, mixed data is a central problem in data mining. Many approaches adopt the idea of k-means, and hence are sensitive to initialisation, detect only spherical clusters, and require a priori the unknown num…

A review of mean-shift algorithms for clustering

A natural way to characterize the cluster structure of a dataset is by finding regions containing a high density of data. This can be done in a nonparametric way with a kernel density estimate, whose modes and hence clus…
