Unsupervised clustering of multivariate circular data.
In this paper, we study an unsupervised clustering problem. The originality of this problem lies in the data, which consist of the positions of five separate X-ray beams on a circle. Radiation therapists positioned the five X-ray beam 'projectors' around each patient on a predefined circle. However, similarities exist in positioning for certain groups of patients, and we aim to describe these s...
متن کاملA Clustering Bayesian Approach for Multivariate Non-Ordered Circular Data
This paper presents a Bayesian model for the clustering of nonordered multivariate directional or circular data. The particular trait of our data is that each single observation is made up of k ≥ 2 nonordered points on the circle. We introduce a hierarchical model that combines a symmetrization technique, Projected Normal distributions and a Dirichlet Process. One parameter is introduced to mod...
متن کاملUnsupervised Clustering of Bioinformatics Data
The development of microarray technologies gives scientists the ability to examine, discover and monitor the mRNA transcript levels of thousands of genes in a single experiment. Nevertheless, the tremendous amount of data that can be obtained from microarray studies presents a challenge for data analysis. The most commonly used computational approach for analyzing microarray data is cluster ana...
متن کاملClustering multivariate functional data
Model-based clustering is considered for Gaussian multivariate functional data as an extension of the univariate functional setting. Principal components analysis is introduced and used to define an approximation of the notion of density for multivariate functional data. An EM like algorithm is proposed to estimate the parameters of the reduced model. Application on climatology data illustrates...
متن کاملImproving Multivariate Data Streams Clustering
Clustering data streams is an important task in data mining research. Recently, some algorithms have been proposed to cluster data streams as a whole, but just few of them deal with multivariate data streams. Even so, these algorithms merely aggregate the attributes without touching upon the correlation among them. In order to overcome this issue, we propose a new framework to cluster multivari...
