Intelligent Agent Systems

Artificial Intelligence Systems that think like humans Systems that think rationally Systems that act like humans Systems that act rationally

What Is Intelligence? Knows the Envrionment (B) Knows What you can do and How you can do that (D) Able to choose the best action (knows Why you choose that) (I)

Agent Definitions No Concensus Definition An Agent is a computional entity which - acts on behalf of a person or other entities in an automous fashion - performs its action with some level of proactivity and/or reactiveness - exhibits some level of the key attributes of learning, cooperation and mobility

Agent Charcteristics Intrinsic Lifespan: Transient to Long-lived Level of Cognition: Reactive to Deliberative Construction: Declarative to Procedural Mobility: Stationary to Itinerant Adaptibility: Fixed to Teachable to Autodidactic Modeling: Of environment themselves, or other agents

Agent Characteristics Extrinsic Locality: Local to Remote Social autonomy: Independent to Controlled Sociability: Autistic, Aware, Responsibility, Team Player Friendliness: Cooperative to Competitive to Antagonistic Interaction: Logistics, Style, Semantic Level

MultiAgent Systems To solve problems that are too large for a centralized single agent to do due to resource limitations. To provide solutions to inherently distributed problems. To provide solutions which draw from distributed information sources

Mobile Agents A mobile agent is a software entity which exits in a software environment and has ability to transport itself from one system in a network to another. A mobile agent system consists of: - An agent model - A life-cycle model - A computational model - A security model - A commutational model - A navigation model
