The
purpose was the design of a fuzzy classifier to differentiate among primary
progressive multiple sclerosis (MS), relapsing remitting MS and non-MS
conditions by 1H-NMR spectroscopy of cerebrospinal fluid. The design
considered the fusion of classifiers based on fuzzy decision trees. We
considered three different datasets (aliphatic region, aromatic region and
the aggregation of both regions). We evaluated for each dataset the
classifier performance by means of two classification quality indexes
(correctness and robustness). Results showed mean classification correctness
and robustness in the intervals [0.92,1] and [0.34,0.50] respectively. The
aggregation of aliphatic and aromatic regions provided the best results.
