Rule Fitness and Pathology in Learning Classifier Systems
2004
Evolutionary Computation
Preserved Fulltext
It has long been known that in some relatively simple reinforcement learning tasks traditional strength-based classifier systems will adapt poorly and show poor generalisation. ...
We distinguish between strong and fit overgeneral rules, and show that although strong overgenerals are fit in a strength-based system called SB-XCS, they are not in XCS. ...
Introduction When applied to reinforcement learning, Learning Classifier Systems (LCS) evolve sets of rules in order to maximise the return they receive from their task environment. ...
