Goal-based agent vs utility-based agent 743534-Goal based agent vs utility based agent

 Goal based agents usually less efficient but more flexible than reflexbased agents A goal basedagent can suit itself based on the environment For example, a goalbased agent can adapt its behavior based on the sensor data 4 UtilityBased AgentsModelbased Reflex Agent Goal and Utilitybased Agents Evaluating Agents Intelligent, Autonomous Agents Agent Anything that can be viewed as perceiving its environment Perception done through sensors Acting upon that environment through actuators Human agent Eyes, ears, and other organs for sensors Hands, legs, mouth, and other body parts for In the first 4, the more sophisticated agents contain the primitive agents The modelbased agent is actually a "modelbased reflex agent", and the goal and utility agents are also modelbased You will notice is that the structure changes fundamentally with the learning agent

Goal based agent vs utility based agent

Goal based agent vs utility based agent-Utilitybased agents the agent is aware of a utility function that estimates how close the current state is to the agent's goal Learning Agents Agents capable of acquiring new competence through observations and actions Components learning element (modifies the performance element) performance element (selects actions) feedback element (critic) exploration element (problem generator) Other Types of Agents The goalbased agent's behavior can easily be changed Utilitybased agents The agents which are developed having their end uses as

Agentbased design Regular programs are procedural First, check to see how much is in the bank account Debit the account by X dollars Return message indicating transaction complete Agentbased designs are reactive Perceive something, react a certain way Similar to GUIbased programming Flow comes from outside environmentAnswer (1 of 2) intelligent means it does things based on reasoning, while rational means it does the best action (or reaction) for a given situation All of the above Answer & Explanation Correct answer 2 Meeting the preference of the user The utilitybased agent focuses more on the utilities and preferences of the user to satisfy the user's needs This property of this agent differentiates it from the other types of AI agents 4) Which of the following does not represent a Goal based

 In this regard, the utilitybased agent is a step above the goalbased agent UtilityBased Agent Characteristics Prior to utilitybased agents, intelligent agents have had only one goal cleanUnlike the previous reflex agents before acting this agent reviews many actions and chooses the one which come closest to achieving its goals, whereas the reflex agents just have an automated response for certain situations Although the goalbased agent does a lot more work that the reflex agent this makes it much more flexible because theReflex, goalbased, or utilitybased) Give a detailed explanation and justification of your choice The patterns which the agent uses are matched against sets of events that occur over time Therefore, the agent needs to maintain knowledge of the past, and, thus, cannot be either a table lookup or simple reflex agent

Modelbased agent an agent that updates its internal model of current world state over time and acts according to this internal state Goalbased agent an agent that acts in order to achieve or maximize its designated goals Utilitybased agent an agent that acts in order to maximize the expected utility of the new state after its action A simplereflex agent selects actions based on the agents current perception of the world and not based on past perceptions A modelbasedreflex agent is made to deal with partial accessibility; Goalbased agents It is not sufficient to have the current state information unless the goal is not decided Therefore, a goalbased agent selects a way among multiple possibilities that helps it to reach its goal Note With the help of searching and planning (subfields of AI), it becomes easy for the Goalbased agent to reach its destination Utilitybased agents These types of agents are concerned about the performance measure The agent

Topics In Ai Agents

Model based reflex agents Modelbased reflex agents are made to deal with partial accessibility; • Goalbased agent Goalbased agents are modelbased agents which sorts goal information that describes situations • Utilitybased agent This is an agent that uses an explicit utility function that maximizes the expected utility • Learning agent This is an agent that improves its behavior based on its experiences and learningUtility Based agent A utility function maps each state after each action to a real number representing how efficiently each action achieves the goal This is useful when we either have many actions all solving the same goal or when we have many goals that can be satisfied and we need to choose an action to perform

The agent is given a goal and hence the agent can now modify it's other aspects as necessary in order to achieve the goal 4 Utility based agents A utility funcions maps a state to a real number, so now the agent can actually obtain a measurement of how successful it UtilityBased Agents These agents are almost like the goalbased agent but provide an additional component of utility measurement which makes them different by providing a measure of success at a given state Utilitybased agent act based not only goals but also the simplest thanks to achieving the goal• An agent program maps from a percepts to actions • There are a variety of designs – Reflex agents respond immediately to percepts – Goalbased agents work towards goals – Utilitybased agents try to maximize their reward – Learning agents improve their behavior over time
