This research is being done in conjunction with IIS-9732562, which is beingperformed by Dorrit Billman in the Psychology Department at GeorgiaInstitute of Technology. The research is concerned with intelligentdecision aids that can be developed by data mining techniques. Experiencehas determined that such systems can learn accurate models, but thatexperts in areas where those models are used in decision aids are oftenreluctant to trust them because they do not, for instance, use the sametests intermediate conclusions or abstractions that the experts have grownto trust. Or they do not use certain factors at all that experts feel tobe relevant. Experts also want models that are stable under small changesin the data being analyzed. Psychologists have discovered factors thatsimplify the learning, understanding, and communication of category andprocess information by humans. This research seeks to explore thesepsychological principles in light of the output of existing KDD algorithmsand then go on to develop and evaluate new KDD algorithms that will provideoutput that is easy for people to learn , use, and communicate to others.With the results of this research, it should be possible to make suchdecision aids more "human centered", so that they will be used more oftenand more effectively in practice.http://www.ics.uci.edu/~pazzani
