  • Classification of Voluntary Cough Airflow Patterns for Prediction of Abnormal Spirometry
    Classification of Voluntary Cough Airflow Patterns for Prediction of Abnormal Spirometry

    In this work, we investigate the feasibility of predicting abnormal spirometry using measurements of the partial flow-volume curve generated during a voluntary cough. A variety of features were extracted from the cough airflow signals and fed to a support vector machine (SVM) classifier. Airflow features and SVM parameters were selected using a genetic algorithm, and accuracy assessed using repeated double cross-validation. This technique is easily performed and does not require expensive equipment. Based on these characteristics, and the results of this study, it has potential for becoming especially useful for mass screening or for testing subjects who are not able to perform conventional pulmonary function testing.

  • DBN-Extended: A Dynamic Bayesian Network Model Extended With Temporal Abstractions for Coronary Heart Disease Prognosis
    DBN-Extended: A Dynamic Bayesian Network Model Extended With Temporal Abstractions for Coronary Heart Disease Prognosis

    Dynamic Bayesian networks (DBNs) are temporal probabilistic graphical models that model temporal events and their causal and temporal dependencies. Temporal abstraction (TA) is a knowledge-based process that abstracts raw temporal data into higher level interval-based concepts. In this paper, we present an extended DBN model that integrates TA methods with DBNs applied for prognosis of the risk for coronary heart disease. More specifically, we demonstrate the derivation of TAs from data, which are used for building the network structure. We use machine learning algorithms to learn the parameters of the model through data. We apply the extended model to a longitudinal medical dataset and compare its performance to the performance of a DBN implemented without TAs. The results we obtain demonstrate the predictive accuracy of our model and the effectiveness of our proposed approach.
