Artificial Intelligence Agent



Agent is anything which precives envoronment through sensors and act upon the environment through actutators.

Rational Agent

Rational agent only do the right thing rather than doing the wrong things.Rational agent choose the precept sequence to maximize the performance measure.

what is Precept Sequence ?

Percept sequence is the sequence of actions choosen by agent to reach the goal state.

Rationality of  Agent depends on

  1. performance measure to be maximize
  2. knowledge about the environment
  3. choosing the right percept sequence
  4. action that performed

Omniscient Agent

omniscient agent is like rational agent but it knows the result or outcome of the action it performed.

Learning Agent

Rational Agent and omniscient agent doesnot operate in unknown environment.But Learning agent can operate in unknown environment.It will perform the action without knowing that will right or wrong and the outcome of the action will be learned and stored in the knowledge base.

Autonomous Agent

The agent operates based on the knowledge given by the designer is  not a autonomous agent.Agent is called autonomous agent when it automatically learn from the environment based upon the knowledge learned it will take decision and action.


Goals and Types of Artificial Intelligence


Goals of Artificial Intelligence

Goals of the Artificial Intelligence is to achive the following things

  1. Reasoning
  2. Machine Learning
  3. Natural Language Processing
  4. Robotics
  5. Perception
  6. Planning
  7. Motion and Manipulation
  8. Creativity
  9. General Intelligence
  10. Speech Recognition
  11. Hand writing Recognition

Types of Artificial Intelligence

Artificial intelligence can be classified into three types based on the level of the machine intelligence

  • ANI (Artificial Narrow Intelligence)
  • AGI (Artificial General Intelligence)
  • ASI (Artificial Super Intelligence)

Artificial Narrow Intelligence

It comprises of basic role tasks such as those performed by chatbots,personal assistants like Siri by Apple and Alexa by Amazon.

Artificial General intelligence

It comprises of human level tasks performed by machine such as self driving cars by uber,Autopilot by tesla.

Artificial Super intelligence

It comprises of machines smarter than human beings.
