Different Goals of AI 89-950 Lecture 1
sensors percepts ? environment agent actions actuators An agent and its environment agent :Something that takes input (percepts) from its environment through sensors and takes actions upon its environment, using actuators. agent function: mapping from percept sequence to an action 89-950 Lecture 1
Automated Agents • Autonomous • Plan • Adaptive • Able to learn • Cooperate with other agents or people • Can face adversary
What is an Agent? PROPERTY MEANING • Situated Sense and act in dynamic/uncertain environments • Flexible Reactive (responds to changes in the environment) • Autonomous Exercises control over its own actions • Goal-oriented Purposeful • Persistent Continuously running process • Social Interacts with other agents/people • Learning Adaptive • Mobile Able to transport itself 89-950 Lecture 1
Properties of environments Observable vs. Partially-observable (complete state of world is available to agent) Deterministic vs. no-deterministic (Stochastic) (no uncertainty about effects of actions) Static vs. Dynamic (do not need to observe while deliberate) Discrete vs. Continuous (state/percepts/actions/time) Single vs. Multiagent (cooperative vs. competitive) 89-950 Lecture 1
