Three-dimensional, on-line color graphics representation in complex decision-making tasks

Making a Low-dimensional Representation Suitable for Diverse Tasks

We introduce a new approach to the training of classiiers for performance on multiple tasks. The proposed hybrid training method leads to improved generalization via a better low-dimensional representation of the problem space. The quality of the representation is assessed by embedding it in a 2D space using multidimensional scaling, allowing a direct visualization of the results. The performan...

Decision-Making Tasks

Decision making with computer graphics

Computer-driven displays have long been thought to help decision making. But the justification for using these devices in decision-making has been long on intuition and short on quantitative analysis. To see if this intuition was right, we conducted an experiment. Eighteen interested and experienced decision-makers in the inventory control field met for twenty class hours of instruction in adva...

Graphics and Environmental Decision Making

S trangely, the combination of geographic information systems (GIS) and visualization remains sufficiently unexplored to warrant a special issue of CC&A. Both fields can claim acceptance, a base of solid theory and practice, and delivery of technology as software products to practitioners. The fields seem to complement one another. yet they have developed in parallel, with little interchange or...

A graphical representation of uncertainty in complex decision making

The analysis of types of uncertainty and how they affect decision making in complex settings can be considerably simplified by addressing three core questions: how uncertain we are, how aware we are of uncertainty and how context and perception affect uncertainty. The continuum nature of the answers to these questions leads naturally to represent uncertainty in a 3D level-awareness-perception p...
