  • Title: [The application of artificial neural network based on ambiguous function to heart sound classification].
    Author: Gao X, Chen K, Jiang T.
    Journal: Space Med Med Eng (Beijing); 1997 Oct; 10(5):353-7. PubMed ID: 11540389.
    Abstract:
    In this study the artificial neural network was applied to heart sound classification. The network input data are ambiguous function, hence the crossterm problem of Wigner distribution is avoided. The simulation result shows that this is an effective technique. A suboptimal network model was proposed by many times of training and checking. The main factors related to network property were also discussed.
