Effect of Pure Error-Based Fitness in XCS

  title={Effect of Pure Error-Based Fitness in XCS},
  author={Martin V. Butz and David E. Goldberg and Pier Luca Lanzi},
The accuracy-based fitness approach in XCS is one of the most significant changes in comparison with original learning classifier systems. Nonetheless, neither the scaled accuracy function, nor the importance of the relative fitness approach has been investigated in detail. The recent introduction of tournament selection to XCS has shown to make the system more independent from parameter settings and scaling issues. The question remains if relative accuracy itself is actually necessary in XCS… CONTINUE READING
