The term Artificial Intelligence comprises of two words ‘ Artificial’  and ‘ Intelligence’ , where, Artificial means ‘copy of something natural’ and ‘Intelligence’ means ‘able to think.’ So, Artificial Intelligence can be defined as a  copy of a human brain with thinking ability. According to  John McCarthy , who is known as the father of AI, “AI is the science and engineering of making intelligent machines, especially computer programs.” The objective of AI is to explore the ways onto a machine that can  reason like a human ,  think like a human and act like a human . Its approach is to train a machine (i.e., a computer or a robot) with the same capabilities as of a human brain. In the future, AI will prove itself as an excellent helping hand. Need for Artificial Intelligence Consider a scenario where a human brain may fail to take an intelligent decision and need someone who can make a wise and intelligent decision for h...

  What is an Agent? An agent can be viewed as anything that perceives its environment through sensors and acts upon that environment through actuators. For example, human being perceives their surroundings through their sensory organs known as sensors and take actions using their hands, legs, etc., known as actuators. Diagrammatic Representation of an Agent Agents interact with the environment through sensors and actuators Intelligent Agent An intelligent agent is a goal-directed agent. It perceives its environment through its sensors using the observations and built-in knowledge, acts upon the environment through its actuators. Rational Agent A rational agent is an agent which takes the right action for every perception. By doing so, it maximizes the performance measure, which makes an agent be the most successful. Note:  There is a slight difference between a rational agent and an intelligent agent. Omniscient Agent An omniscient agent is an agent which knows the actual outc...
