The Aphasia Diagnoser was developed for educational purposes and is based on a database of 254 aphasic patients. Two different approaches are taken: 1) Classification with neural networks for group studies, 2) nearest neighbour ranking for detailed information about similar, single patients. The Aphasia Diagnoser is used as a tutorial by engineering students and by medical students in a course concerning classification methods and their applications in medicine. The database contains diagnoses of aphasia types and the results of an aphasia test battery (the Aachen Aphasia Test, AAT). In 150 of these patients brain lesions were visualized with Computer Tomography (CT). The lesion data was standardized by transforming the coordinates of the lesions to a 3D-reference brain and projected onto 12 equidistant frontal magnetic resonance imaging (MRI) slices. Lesions from different patients can thus be compared to each other. The AAT-profiles in the database were used to train artificial neural networks for classification of the aphasia type. First a coarse classification was performed by using an assessment of spontaneous speech. This classification can be done without the complete AAT. The classifier produced correct results in 86% of the test cases. For a more accurate diagnosis, further AAT subtests have to be performed. A commercial software product, Feature Selector for DataEngine, was used to select four features from 30 available features. This second classifier produces correct results in more than 92% of the test cases. Another approach is implemented with the nearest neighbour method based on the root mean square (RMS) distance in the space of normalized features. Lesion profile and aphasia diagnosis of those patients in the database are shown, whose AAT results are most similar to the user's input.

Instead of requiring the nominal and faulty nonlinear systems to match each other directly in some proper sense, three sets of LTI models are employed to approximate the faulty, reconfigured and nominal nonlinear systems respectively with respect to the on-line information of the operating system, and a set of compensating modules are proposed and designed so as to make the local LTI model approximating to the reconfigured nonlinear system match the corresponding LTI model approximating to the nominal nonlinear system in some optimal sense. The compensating modules are designed by the Pseudo-Inverse Method based on the local LTI models for the nominal and faulty nonlinear systems. Moreover, these modules should update corresponding to the updating of local LTI models, which validations are determined by the model approximation errors and the optimal index of local design.

But, astonishing enough, in many cases this is sufficient for an experienced practitioner to attend successfully. First necessity for a scientific evaluation of such sort of database is to get as much specific information as available from as many patients as possible. This is essential because of the great variability of human diseases. The next step is to extract relevant data from the database addressed to the question of interest and the anticipated answers and models, which assign relevance to data. The data has to be objective, reliable, constant, and independent. The independence is the main topic of this paper. Several methods like analysis of variance, analysis of discriminance, multiple regression and factor analysis offer the possibility to control the interdependence of data. Factor analysis has the advantage that it is based on a mathematical model, and does not ask for normal distribution of the data. Factor analysis describes the correlation of many variables by few independent factors. The number of factors which can be extracted from a correlation matrix is a reliable criterion for inherent independent information in that matrix. Several data sets were analyzed, which were gained from the Aphasia Database, such as different groups of patients, groups of symptoms, and symptoms in time sequence. 26 aphasic symptoms (e.g. dysarthria, paraphasias, neologisms, agrammatism, etc.) documented in reports of the 265 aphasic patients provide 3 factors. If the symptoms were graded according to the severity of disability in the individual cases, then 5 factors were extracted. The factors had different relationships (loadings) to the symptoms. Although the factors were gained only by computations, they seemed to express some modular features of the language disturbances. This phenomenon, that factors represent superior aspects of data, is well known in factor analysis. Factor I mediates the overall severity of the disturbance, factor II points to expressive versus comprehensive character of the language disorder, factor III represents the granularity of the phonetic mistakes, factor IV accentuates the patients’ awareness of his disease, and factor V exposes the deficits in communication. Sets of symptoms corresponding to the traditional symptoms in Broca and Wernicke aphasia may be represented in the factors, but the factor itself does not represent a syndrome. It is assumed that this kind of data analysis shows a new approach to the understanding of language disturbances, which should represent functional entities of the brain more closely than the traditional clinical descriptions do. }, booktitle={ESIT 2000 Final Programme and Proceedings (Abstracts and CD)}, year={2000}, publisher={Verlag Mainz, Wissenschaftsverlag, Aachen}, pages={1}, crossref={ESIT2000}, keywords={Aphasia, classification in medicine, data mining, factor analysis, feature selection.}, note={(extended abstract)} } @misc{lab98, author={M.
