✦ Synopsis

A theory viewing human problem solving as a memory search of information organized into a hierarchy of categories was evaluated through the application of informationprocessing techniques to medical diagnosis. Information-processing methodology essentially involves the determination of the thought processes or symbolic manipulations necessary to the performance of a task and their precise specification as a computer program or model. To this end, a boarded clinical neurologist was asked to "think aloud" while solving a number of diagnostic problems. The information processes, decision rules and other evaluation criteria characteristic of diagnosis were extracted from these subjective verbal reports and incorporated in a computer program of the diagnostic process in medicine. The results supported the theory of diagnostic problem solving and the computer model based on this theory proved sufficient to perform diagnosis.

System monitoring and diagnosis is a research area that has received a growing interest from both the signal processing community and the control community in the recent years. Indeed, the development of new sensors makes it possible to record variables on a system that were not acquired previously.
