SCI VISUAL DATA ANALYSIS

II. Learning Objectives:

Upon successful completion of this course, the student will be able to:

interpret and analyze complex analytic expressions, large experimental or computer simulation data sets,
visually quantify multidimensional physical properties such as eigenvalues-eigenvectors with glyphs,
apply principles of graphical excellence to complex ideas associated with large data sets or complex analytical functions with clarity, precision, and efficiency,
compose a final project in a well organized and well designed visual format using multimedia or web software.

III. Justification

Computer graphics have become increasingly useful for many disciplines, including art and architecture, as well as for engineering and science. Engineers and scientists use graphics software for analysis and interpretation in addition to presentation. The introduction of computer graphics as an analytical research tool was largely motivated by the National Science Foundation which created four supercomputing centers in the late 80s. Scientists and engineers have increasingly used supercomputers to simulate complex phenomena, typically three dimensional, that resulted in massive data sets. Similarly, computer-controlled experiments in the laboratory have also created massive three dimensional data sets such as MRI and X-Ray CAT scans. These massive data sets created a new problem in that traditional graphical techniques designed for presentation were inadequate for analysis and interpretation. Hence the name "visualization", short for visual data analysis, was coined to emphasize analysis and interpretation.

The need for visual data analysis has penetrated almost every discipline that encounters these large data sets. Because large data sets are encountered in the course of a senior project or graduate level research project, this course is oriented as a problem solving class project. Students are required to define a research problem as their class project that can benefit from implementing visual methods and techniques introduced in the class. Because of the emphasis on research, this course is suited for both 4000 level undergraduate class and 5000 level graduate class where senior projects, M.S. and Ph.D. research projects can encounter large complex data sets. As a special study this class was taken mostly by graduates and the Department of Computer Science also indenpently approved this class for graduate credit.

No credit is given for developing or programming visual interfaces although it is expected that students must demonstrate proficiency in programming as a prerequisite.

With resources provided in the ACITC: 1) Scientific Visualization and Modeling Classroom and 2) University Visualization and Animation Laboratory, students learn how to use state-of-the-art visual tools in a systematic and rational way, independent of the source of data (experimental, numerical, or analytical) to gain insight into their data or complex analytic functions. Access to NSF supercomputer time is also available from the NCSA for class projects that require numerical solutions to complex boundary value problems.
