Abstract

The diagnostic problem is posed as recognizing patterns in rejection data and thesubsequent mapping to causes. A new network architecture has been proposedwhich should overcome many of the disadvantages of the existing diagnostictools. The network is based on the authors’ earlier work (Ransing et al...
