Mosiac Matrix, Mosaic Matrix, Hiroaki Kobayashi, Kazuo Misue, Jiro Tanaka · 2013
Due to the displays' limitation in size, it is difficult to obtain an overview of high-dimensional data in the area of the display that displays the results of visualization. In this paper, we aimed to obtain an overview of the high-dimensional data in a limited area of the screen. We developed Colored Mosaic Ma- trix as a method to obtain an overview of high-dimensional data. Colored Mosaic Matrix is a visualization method for high-dimensional categorical data, using a color representation of the features. By representing the quantitative data in units of categories, it enables the visualization of high-dimensional data with a large number of records. As a result of investigating the readability by experiments, we have found our method to be useful in obtaining an overview of high-dimensional data.
