Curve Tailoring with Inter-Active Computer Graphics
Dennis, J.E. Jr.
Woods, Daniel J.
We are exploring ways to use the increasingly common graphics workstations (we use a SUN) to make numerical computation more convenient. The particular experiment reported on here involves the use of the mouse to obtain input from the user that he usually supplies as a subroutine. Specifically, the user specifies a set of one-dimensional data and a model whose parameters are to be chosen to best fit the data. He does not specify what optimality criterion is to be used to pick the parameters. Instead, he is asked to point out his preference from displayed prospective fits. This information is used by the Nelder-Mead simplex algorithm to improve the fit during the exploratory data analysis phase. The information is also used to determine a fitting criterion that is consistent with the selections made during the process. It is then possible to determine a final set of parameters that are optimal for this criterion.
