Icon-based Visualization of Large High-Dimensional Datasets
نویسندگان
چکیده
High dimensional data visualization is critical to data analysts since it gives a direct view of original data. We present a method to visualize large amount of high dimensional data. We divide dimensions of data into several groups. Then, we use one icon to represent each group, and associate visual properties of each icon with dimensions in each group. A high dimensional data record will be represented by multiple different types of icons located in the same position. Furthermore, we use summary icons to display local details of viewer’s interests and the whole data set at meantime. We show its effectiveness and efficiency through a case study on a real large data set.

High Dimensional Data Visualization Using 3-D Icons
In this paper we present a method to visualize large amount of high dimensional data. High dimensional data visualization is very important to data analysts since it gives a direct and natural view of data. In our method we use one icon to represent one group of dimensions. Then we choose features of the icon to display the dimensions within each group. We have performed experiments on a real d...
متن کاملAn Interactive Visualization Model for Large High-dimensional Datasets
Data visualization gives a direct view of complex data, which is especially helpful for analysis of large high dimensional datasets. However, existing methods often lose simplicity and clarity while rendering large amount of complex data. In this paper, we discuss some essential properties that a data visualization system should have. Also we present an interactive data visualization model whic...

متن کاملSFLA Based Gene Selection Approach for Improving Cancer Classification Accuracy
In this paper, we propose a new gene selection algorithm based on Shuffled Frog Leaping Algorithm that is called SFLA-FS. The proposed algorithm is used for improving cancer classification accuracy. Most of the biological datasets such as cancer datasets have a large number of genes and few samples. However, most of these genes are not usable in some tasks for example in cancer classification....
متن کاملScatterplot 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 ...
