Case-based reasoning (CBR)is a process used for computer processingthat tries to mimic the behavior of a human expert in making decisions regarding a subject and learn from the experience of past cases.CBR has demonstrated to be appropriate for working with unstructured domains dataor difficult knowledge acquisition situations,such as medical diagnosis, where it is possible to identify diseases such as:cancer diagnosis, epilepsy prediction and appendicitis diagnosis. Someof the trendsthat may be developed for CBR in the health science are oriented to reduce the number of features in highly dimensional data.An important contribution may be the estimation of probabilities of belonging to each class for new cases.In this paper, in order to adequately represent the database and to avoid the inconveniences caused by the high dimensionality, noise and redundancy, a number of algorithms are used in the preprocessing stage for performing both variable selection and dimension reduction procedures. Also,a comparison of the performance ofsome representative multi-classclassifiers is carried out to identify the most effective oneto includewithin a CBR scheme. Particularly, four classification techniques and two reduction techniques are employed to make a comparative study of multi-classclassifiers on CBR.
