GENERATING FUZZY RULES FOR PROTEIN CLASSIFICATION

This paper considers the generation of some interpretable fuzzy rules for assigning an amino acid sequence into the appropriate protein superfamily. Since the main objective of this classifier is the interpretability of rules, we have used the distribution of amino acids in the sequences of proteins as features. These features are the occurrence probabilities of six exchange groups in the seque...

Boosting fuzzy rules in classification problems under single-winner inference

In previous studies, we have shown that an Adaboost-based fitness can be successfully combined with a Genetic Algorithm to iteratively learn fuzzy rules from examples in classification problems. Unfortunately, some restrictive constrains in the implementation of the logical connectives and the inference method were assumed. Alas, the knowledge bases Adaboost produce are only compatible with an ...

For just as long, however, they appear to have been proceeding with littl...
