High-dimensional data visualization

3D Visualization of High-Dimensional Discrete Data

The need for effective visualization of highdimensional data is still in demand in the field of scientific data analysis. In this paper, we present interactive 3D hyperedges as a 3D metaphor for visualizing highdimensional discrete datasets with an emphasis of enhancing the separation of data instances in a dataset by means of statistical significance. The effectiveness of the proposed visual m...

Visualization & Data Mining for High Dimensional Datasets

On the visualization of high-dimensional data

Computing distances in high-dimensional spaces is deemed with the empty space phenomenon, which may harm distance-based algorithms for data visualization. We focus on transforming high-dimensional numeric data for their visualization using the kernel PCA 2D projection. Gaussian and p-Gaussian kernels are often advocated when confronted to such data; we propose to give some insight of their prop...

Scatterplot layout for high-dimensional data visualization

Multi-dimensional data visualization is an important research topic that has been receiving increasing attention. Several techniques that apply scatterplot matrices have been proposed to represent multi-dimensional data as a collection of two-dimensional data visualization spaces. Typically, when using the scatterplot-based approach it is easier to understand relations between particular pairs ...

Class Visualization of High - Dimensional Data withApplicationsInderjit

We consider the problem of visualizing high-dimensional data that has been categorized into various classes. Our goal in visualizing is to quickly absorb inter-class and intra-class relationships. Towards this end, we introduce class-preserving projections of the multidimensional data onto two-dimensional planes which can then be displayed on a computer screen. These class-preserving projection...
