Interactive Visualization of Multidimensional Data

چکیده

Interactive data visualization concerns the real time manipulation of sampled and computed data for comprehensive display. The goal of the visualization is to bring to the user a deeper understanding of the data as well as the underlying physical laws and properties. In this survey paper I focus on two problem areas relating to interactive data visualization. The rst is in data reduction and dealing with the computation of error-bounded reduced detail meshes with topological correctness. The second is in data reconstruction from scattered point scans and dealing with accurate spline models which support interactive querying and manipulation. For each of these problem areas I survey some of the related research and simultaneously present some of our own recent results.

Interactive Visualization of Multidimensional Data Academic Dissertation in Interactive Technology

Information visualization techniques can aid us in gaining insight into abstract and complex data, and help us when we need to form a mental image thereof. One of the challenging areas in information visualization is the visualization of multidimensional data. The problem arises when we need to consider a large number of data variables and their relationships simultaneously, often without a wel...

ProxiViz: an Interactive Visualization Technique to Overcome Multidimensional Scaling Artifacts

Projection algorithms such as multidimensional scaling are often used to visualize high-dimensional data. However, when attempting to interpret the visualization of the resulting 2D projection, users are faced with artifacts. This poster introduces ProxiViz: an interactive technique to provide better insights about the original data-space. Primary results of a controlled experiment show that Pr...

Geo-visualization Support for Multidimensional Clustering

In this paper we consider how multidimensional clustering can be complemented by interactive visualization. We propose a link between geovisualization and data mining systems for supporting an iterative analysis cycle, including data pre-processing and visual exploration, automatic detection of clusters in multidimensional space of user-selected attributes, and visual analysis of cluster analys...

Interactive visualization of multidimensional coincidence spectra

The paper presents direct visualization techniques of multidimensional nuclear spectra as well as visualization techniques based on projections of embedded subspaces. While the first group of graphical models is limited to four dimensions, the second one can be theoretically extended to any dimension. The presented algorithms of visualization have been implemented in nuclear data acquisition, p...

Visualization Methodology for Multidimensional Scaling

We describe methodology for multidimensional scaling based on interactive data visualization. This methodology was enabled by software in which MDS is integrated in a multivariate data visualization system. The software, called “XGvis”, is described in a companion paper (Buja, Swayne, Littman, Dean and Hofmann 2001), that lays out the implemented functionality in some detail; in the current pap...

Interactive Data Exploration Using Mds Mapping

Interactive exploratory data analysis can be realised by using dimensionality reduction techniques integrated in data visualization software. This work presents an adaptation of one multidimensional scaling algorithm to provide it with generalization capability, allowing the display of new data on an existing mapping. The ensuing relative mapping is used to help the understanding of classificat...
