autonomy / autonomous action
For the purposes of this book, the ability of a piece of software to determine for itself how to achieve its delegated goal/task.
situated agent
An agent that inhabits (is situated in) some environment.
adjustable autonomy
The idea that we have some control over how autonomous an agent is: for example, we might specify that an agent should verify certain decisions with us before proceeding them.
agent architectures
A software architecture for autonomous decision making: specifies the data structures, control flow, and, usually, the methodology to be used for constructing an agent for a particular task in a particular environment.
control systems
na
physically embodied agent
An agent such as a robot, whose decision-making and action directly affect the physical world.
software agent
An agent that inhabits a software environment, as opposed to a physically embodied agent.
functional system
A system such as a compiler, which can be understood as a function f:D->R from some domain of values D to some range R - in contrast to a reactive system.
reactive system
A system that maintains an ongoing interaction with its environment.
episodic environments
A type of task that contains of a number of discrete 'episodes' which do not interact with each other - what an agent does in one episode has no influence on other episodes, so the consequences of action are limited to the episode where the action was performed.
reactivity
The ability of an agent to be aware of and repond to changing environmental circumstrances.
proactivity
Goal-directed behavior; taking the initiative; not being solely by events.
social ability
The ability of an agent to engage in analogues of the social processes that we all engage in every day: not just communication, but cooperation, coordination and negotiation.
intentional stance
The idea of explaining the behaviour of agents by attributing mental states like belief and desire together with rational acumen.
mental state
The cognitive makeup of an agent: its beliefs, desires, intentions, hope, fears, ...
folk psychology
na
intentional system
A system that can be explained by the intentional stance.
physical stance
The idea of explaining or predicting the behaviour of a complex system by reference to its design or structure - contrast with the intentional stance.
design stance
The idea that we understand the behaviour of a complex entity by considering its design.
runs
A computation of an egant/environment system: an interleaved sequence of environment states and actions.
purely reactive agent
An agent that does no reasoning whatsoever: it simply maps a current situation to corresponding action.
tropistic agents
Another term for purely reactive agents.
percepts
The 'sensor data packages' received by an agent.
task specification
A high-level description of a task to be carried out.
utility
A numeric measurement of how good an outcome is for an agent: outcomes with higher values are preferred over outcomes with lower values - while it is sometimes useful to think of utility as money, they are not the same thing!
optimal agent
An agent is optimal if it maximizes expected utility.
expected utility
The value/payoff that an agent can expect to earn on average.
bounded-optimal agent
An agent that behaves as well as any agent could behave given the computational resources available to it.
predicate task specification
A way of specifying tasks for agents, in which we define a task as a predicate over runs: an agent is 'successful' on a run if that run satisfies the predicate.
achievement tasks
A task in which an agent has to achieve or bring about some state of affairs.
maintenance tasks
A maintenance task is one in which an agent must maintain some state of affairs.
agent synthesis
The process of constructing an agent for a particular task environment.
