Knowledge Discovery in Repeated Very Short Serial Measurements with a Blocking Factor. Application to a Psychiatric Domain
Jorge Rodasa and J. Emilio Rojob

Abstract: A new hybrid methodology for Knowledge Discovery in Serial Measurement (KDSM) and the results of applying it to psychiatry are presented in this paper. In the application domain where serial measurements are repeated and very short (i.e. very few parameters), traditional measure methods for series analysis are inappropriate. Moreover, some information is non-serial but is closely connected to serial measurements. For this reason, common statistical analysis (time series analysis, multivariate data analysis . . .) and artificial intelligence techniques (knowledge based methods, inductive learning) used independently provide often poor results
because of the characteristics above and it is necessary a suitable way of analyzing these situations. KDSMis built as an hybrid methodology, specially designed to obtain knowledge from repeated very short serial measurement, in order to overcome the limitations of Artificial Intelligence or Statistics techniques. Novel knowledge about electroconvulsive therapy behavior was obtained once KDSM was applied to this specific domain. Thus, KDSM gives a possible solution to a knowledge problem.
