What are intelligent agents?

  • Intelligence of the agent is heavily influenced by its mobility & autonomy (agency)
  • How does an intelligent agent work?

    • It uses sensors to perceive environment, processing to manipulate data, learning to update knowledge & effectors to take actions & communicate
  • An agent can be considered as a sub-system
  • Modular unit readily added to existing or new applications
  • What is MAS?

    • MAS: multi-agent system
    • It is also distributed artificial intelligence (DAI)
  • The system has more than one agent working either independently or co-operatively or competitively
  • How do the agents communicate?

    • May or may not be necessary to communicate
    • Independent: agents work independently without knowledge of one another
    • Communicative: agents work & communicate with one another
  • Blackboard architecture: central controller manages the blackboard & co-ordinates agents
  • KQML: Knowledge Query & Manipulation Language
  • How do agents use KQML?

    • KQML provides framework for various agents to communicate & understand one another
    • Using performatives (messages)
  • Information levels:
  • Communication: model
  • Message: language, ontology (vocabulary)
  • Content: specific lang.
  • How do agents interact?

    • Co-operation: divide-conquer, distributed, performance status
    • Kabash system & used in design where conflicts may arise that require balancing to attain global optima
  • Competition: agents working in conflicting environment for competitive advantage; no sharing, more obstruction than co-operation
