Fuzzy Diagnosis by Score-Based Tests — Implementation Issues
Sorina Zahan · Studies in fuzziness and soft computing · 2000
The aim of this contribution is to discuss some implementation issues related to a rather common element of the medical diagnosis, namely the score-based test. The presentation includes several implementation possibilities and discusses their advantages and drawbacks. Emphasize is given to fuzzy approaches that use fuzzy scoring of the diagnostic criteria, for which an implementation method that avoids losses of diagnosis accuracy is derived. The performances of different implementation possibilities are analyzed in the context of an untypical score-based test. The experiments carried out using different clinical cases revealed that the diagnosis performances not only depend on the nature of the scores, but also on the implementation option.
