Abstract:

This paper studies UCS, a learning classifier system (LCS) derived from XCS that works under a supervised learning scheme. A complete description of the system is given. Besides, we introduce a fitness sharing scheme to UCS and analyze UCS both with fitness sharing and without fitness sharing. Results show the benefits of fitness sharing in all the tested problems, specially those with class imbalances. We also compare UCS with XCS and analyze how the fitness pressure works under each approach.
