Classifier Fitness Based on Accuracy
  • S. Wilson
  • Mathematics, Computer Science
  • Evolutionary Computation
  • 1 June 1995
TLDR
We investigate a classifier system, XCS, in which each classifier maintains a prediction of expected payoff, but the classifier's fitness is given by a measure of the prediction's accuracy. Expand
