    learn and influence each other in their
    learning process?

27
Exchanging Advice
  • Learning for Multi-Agent Systems
  • Use communication to improve learning performance
  • Environments
  • Multiple agents dealing with similar problems
  • Agents use different learning techniques
  • Expected features
  • Improved resistance to local minima
  • No pre-selection of the best algorithm
  • Group performs better than the best of its
    individuals
