| Research Abstract |
The aim of this project is to validate the effectiveness of data visualization technique like Textile Plot for analysis of large complex data to find out new aspects of underlying phenomena and result in a better modeling. The project has been conducted through real application to real problems. Three application fields are taken into account in this project, genome analysis, financial data analysis and marine survey analysis. It has been shown that Textile Plot is a quite powerful tool in finding new genomes compared with a traditional way of visualization LD Display. We have developed a new algorithm to be able to deal with super high, for example several million dimensional data, which is common in genome analysis. In the field of finance, it is shown that Textile Plot is a powerful tool in describing difference of hedge fund operations as well as FX rates. We have conducted cooperative research works with Commonwealth Science and Industry Research Organisation in the field of marine survey data analysis. We could find several interesting aspects of the effect of environmental changes to seabed or estuary fauna by using Textile Plot together with PP plots. It led us to develop a new distributional modeling of the weight and number of such animals, as a stationary distribution of a stochastic difference equation for the growth.
