Dec 12, 2021 · For instance, in fields such as Reinforcement Learning, Multi-Agent Systems, Game Theory, Markov Decision Processes. In an intuitive sense, it is clear to me what an agent is; I was wondering whether in AI it had a rigorous definition, perhaps expressed in mathematical language, and shared by the various AI-related fields.
Dec 12, 2021 · 1. A learning agent can be defined as an agent that, over time, improves its performance (which can be defined in different ways depending on the context) based on the interaction with the environment (or experience). The human is an example of a learning agent. For example, a human can learn to ride a bicycle, even though, at birth, no human ...
Aug 28, 2016 · The job of AI is to design an agent program that implements the agent function — the mapping from percepts to actions. After that, in section 2.4.1, they write. Notice the difference between the agent program, which takes the current percept as input, and the agent function, which takes the entire percept history.
Once the signal is detected, they interpret it, make a decision, and produce an action or output. These AI types of agents can be found in smart home systems or thermostats. Model-based Reflex Agents. This type of AI agent maintains an active internal state, gathering information about how the world works and how its actions affect it.

Oct 29, 2018 · For an example of a non-goal based utility agent consider a form of a partisan sudoku in which players compete to control regions on the gameboard by placement of weighted integers. In a game with 9 regions, the goal based agent seeks to control a specific number of regions at the end of play. If the agent is conservative, the goal might be 5 ...
Mar 5, 2020 · I'm adding this NLL to my Iceberg/Sagent intelligent agent AI. Theoretically, that will be more like what you mean by "AI" As the first answer says, "AI as any artifact that makes a decision" I would elaborate by saying, "An AI performs an action by making a decision" My Iceberg/Sagent AI uses a layer above python modules turning them into Sagents (or Intelligent agents).
Nov 19, 2018 · 5. The agent in RL is the component that makes the decision of what action to take. In order to make that decision, the agent is allowed to use any observation from the environment, and any internal rules that it has. Those internal rules can be anything, but typically in RL, it expects the current state to be provided by the environment, for ...
6. When we use the term rationality in AI, it tends to conform to the game theory / decision theory definition of rational agent. In a solved or tractable game, an agent can have perfect rationality. If the game is intractable, rationality is necessarily bounded. (Here, "game" can be taken to mean any problem.)
Feb 9, 2021 · Agent. The other answer defines an agent as a policy (as it's defined in reinforcement learning). However, although this definition is fine for most current purposes, given that currently agents are mainly used to solve video games, in the real world, an intelligent agent will also need to have a body, which Russell and Norvig call an architecture (section 2.4 of the 3rd edition of Artificial Intelligence: A Modern Approach, page 46), which should not be confused with an architecture of a ...
