    In the past few decades, machine learning tools have been successfully used in several medical diagnostic problems. While they often significantly outperform expert physicians (in terms of diagnostic accuracy, sensitivity and specificity), they are mostly not being used in practice. One reason for this is that it is difficult to obtain an unbiased estimation of the diagnosis's reliability. We disc... View full abstract»

    We describe a knowledge-based system for microbiological laboratory data validation and bacterial infection monitoring. The knowledge base has been obtained from international standard guidelines for microbiological laboratory practice, from experts' suggestions and from data mining. In this paper, we evaluate the system in terms of accuracy on a test data set. View full abstract»

    A system based on a fuzzy finite state machine (FFSM) has been developed for evaluating cytological features derived directly from a digital scan of breast fine needle aspirate (FNA) slides. The system uses computer vision techniques to analyse cell nuclei in order to extract determinate features and to try to find, by means of genetic algorithms (GA), the ideal FFSM that is able to classify them....

    The determination of gestational age in newborn children is fundamental to the evaluation of their survival possibilities. In many cases, when the qualified pre-natal attendance has not occurred, the post-birth evaluation of the gestational age becomes the only alternative. This paper presents a medical image retrieval system whose goal is to help to confirm a new method (called FootScan) for gest... View full abstract»

    Palliative care units are hospital services that assist advanced-state terminal patients. These patients are geographically distributed and some hospital tasks such as the organization of visits, the management of medicines, and the analysis of patients are difficult to manage. Here, a multi-layer computer system is proposed. The communication, information system, and multi-agent layers are descri... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (217 KB) | HTML iconHTML

    Modern and effective biomedical research needs new and effective methods. Use of 96-well micro-titre plates allows the performance of many experiments and samples under the same conditions. The methods used to determine cell numbers in these plates are all end-point methods. These methods allow only one determination per plate, and the cells are lost. Usually, such assays are performed according t... View full abstract»

    Describes several types of efficiency enhancements of "classical" rule-based diagnostic expert systems. The blackboard control structure enables one to explore more knowledge bases of the same syntax in parallel, the taxonomy structures make fast zooming of attention possible and provide an additional inference mechanism based on inheritance principles. In addition to these mechanisms, we describe... View full abstract»

    A novel autonomous evolutionary algorithm for the construction of decision trees is presented, together with an analysis of different medical data sets. The algorithm's capability to self-adapt to a given problem is used as a measure to predict if some data set is just difficult or whether it is impossible to analyze. If a specific data set doesn't include enough or proper information for the crea... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (205 KB) | HTML iconHTML

    We examine the prescribing process in a hospital to see whether information systems failure contributes to the occurrence of prescribing errors. J.T. Reason's (1990) model of organisational failure suggests that this may be the case. Reason identified circumstances in work systems and processes where errors may occur. While Reason's model has been applied in a medical context, it has not previousl... View full abstract»

    The increasing storage of vast amounts of information on computers and the rapidly increasing size of databases stored online has the population (and even many politicians) worried about invasion of privacy. This paper examines some possible ways in which privacy maybe invaded by the use of medical databases, particularly during the analysis and publication of results. View full abstract»

    The spread of electronic use of data in various areas has pushed the importance of data quality to a higher level. Data quality has syntactic and semantic components; the syntactic component is relatively easy to achieve if supported by tools (either off-the-shelf or our own), while the semantic component requires more research. In many cases such data come from different sources, are distributed ... View full abstract»

    In the last few decades, medical data has mainly been a by-product of daily operations. In general, not much has been used for analytical purposes, other than reporting and simple statistics. Just recently, it has become clear that data are important assets if used for analyses that help decision-making. To be able to analyse the data, one needs to have full access to the relevant sources. This ma... View full abstract»

    We study a new approach to rule induction from medical data sets with the help of physicians' assessment of the progressing solution in order to find new patterns in the available data. A method for the automatic extraction of rules is presented which is based on the evolutionary induction of decision trees and on automatic programming. The method is applied to a cardiovascular database. Several s... View full abstract»

    Searching for new rules and new knowledge in problem areas, where very little or almost none previous knowledge is present, can be a very long and demanding process. In our research we addressed the problem of finding new knowledge in the form of rules in the diabetes database using a combination of decision trees and association rules. The first question we wanted to answer was, if there are sign... View full abstract»

    The pulse waveform plays an important role in pulse diagnosis, which is the key technique in traditional Chinese medicine. However, its baseline wander introduced in the acquisition process will result in misdiagnosis. Therefore a wavelet based cascade adaptive filter to remove this wander is presented. This cascade adaptive filter works in two stages. The first stage is a discrete Meyer wavelet f... View full abstract»

    Deals with the problem of decomposition of surface electromyograms (SEMG). According to the physiological facts, a multiple-input multiple-output (MIMO) is used. The measured signals are taken as the channel responses corresponding to the motor-unit action potentials (MUAPs) convolution by the innervation pulse trains. The decomposition is based on the third-order cumulants whose values enter as c... View full abstract»
