The graphical representation method, Robust CoPlot, is a robust variant of the classical CoPlot method. CoPlot is an adaptation of multidimensional scaling (MDS), and is a practical tool for visual inspection and rich interpretation of multivariate data. CoPlot enables presentation of a multidimensional dataset in a two dimensions, in a manner that relations between both variables and observati...

Combined with the development of current educational environment, physical education will replace English as third subject in future. The breakthrough teaching is also gradually changing from general form to today’s smart education. In era big data, can apply this technology. action scenarios based on operations such correction detailed actions or monitoring and identification key are common. T...

Topological persistence has proven to be a promising framework for dealing with problems concerning the analysis of data. In this context, it was originally introduced by taking into account 1-dimensional properties of data, modeled by real-valued functions. More recently, topological persistence has been generalized to consider multidimensional properties of data, coded by vector-valued functi...

Interpreting the information hidden in multidimensional data can be considered as a challenging and also a complicated task. The compression, dimension reduction and visualization of these multidimensional data provide ways to better understanding and interpretation of the problem. Usually, dimension reduction or compression is considered as the first step to data analysis and exploration. Here...

Aim of this paper is to describe an unified framework for the treatment of network data with interpretative tools of Multidimensional Data Analysis. Social Network Analysis is an analytical framework concerned with the detection and interpretation of ties patterns among social actors, while Multidimensional Data Analysis is a collection of techniques to explore different kind of statistical dat...

This paper aims at providing a survey of recently developed multidimensional methods in the field of spatial data and policy analysis. After a brief methodological introduction, various multidimensional techniques for data analysis are discussed. Much emphasis is placed on the treatment of soft (ordinal or qualitative) data. Next, several multidimensional methods for policy analysis (multi-obje...
