A Formal Framework for Positive and Negative Detection Schemes

F. Esponda, S. Forrest, P. Helman
2004 IEEE Transactions on Systems Man and Cybernetics Part B (Cybernetics)  
A new match rule is introduced, called -chunks, and the generalizations induced by different partial matching rules are characterized in terms of the crossover closure.  ...  Partial matching rules generalize the set of allowable (or unallowable) patterns, and the choice of matching rule affects the tradeoff between positive and negative detection.  ...  ACKNOWLEDGMENT The authors would also like to thank J. Holland, A. Tyrrell, W. Langdon, and the anonymous reviewers, who's comments greatly improved the presentation of this work.  ...
