Correct Answer - Option 4 : Utility based agent
The correct answer is "option 4".
CONCEPT:
According to computer science, Artificial Intelligence is the study of "intelligent agents" or "rational agents and their environment".
Agent: Agent is those that work or act in their environment.
Environment: It is the surrounding of an agent.
An agent takes input from the environment through sensors & delivers the output to the environment through actuators.
EXPLANATION:
option1: Simple reflex agent acts on the basis of current percept and ignores percept history i.e. all the history an agent has perceived till date.
option2: Model-based agents have a model i.e. knowledge about how things happen in the whole world & based on the model it performs actions.
option3: Learning agents learn from past experiences and automatically adapt through learning. It has learning capabilities.
option4: Utility-based agents choose actions on the basis of utilities or preference and chooses the actions that maximize the expected utility. Utility describes the happiness of the agent.
Hence, Utility-based agents deal with happy & unhappy agents.
1. Sensors are used to detect any type of change in the environment & inform other electronic devices.
2. Actuators convert energy into motion & are responsible for the movement of the system.
3. Rational agent acts in a way that improves the performance measure with any possible actions.
